Handle canonical response from subcommands
In continuation to PR #1805, when the ycmd server returns a canonical type (boolean, number, string, etc.), we should print it to the user.
For example, this applies to the `SolutionFile` C♯ subcommand which only returns a string (actually, this could be improved in the completer).
This also fixes a thrown exception when the response is not iterable (a number for example).

Handle boolean responses from ycmd subcommands
`ServerReady`, `ServerRunning`, and `ServerTerminated` C♯ subcommands could return a traceback or nothing in Vim because ycmd returns a boolean as the response of these commands.
Fix this by echoing `Yes` when the response is `True`, `No` otherwise.
Refactor the `RunPostCommandActionsIfNeeded` function to improve readability.

Introducing :YcmToggleLogs command
Two approaches were proposed in PR #1753:
- open the stdout and stderr logfiles in Vim windows or close them if already opened: `:YcmToggleLogs`;
- open one of the logfiles in the preview window by specifying it as an argument in the command: `:YcmShowLog <stdout|stderr>`.
This PR merges both approaches by adding an optional argument (`Stdout` or `Stderr`) to the first approach. When no argument is given, both logfiles are opened (or closed if already opened).
With this approach, we cannot use the preview window because only one such window is allowed by Vim. So, we simulate it by adding properties specific to the preview window (horizontal split, height, etc.)
Since they are multiple ways to open a file in Vim, I added a generic function `OpenFilename` for this. It makes easy to customize the way logfiles are opened and could be useful for new features.
Tests were a pain to add and I am not sure of the way I implemented them. If someone could review them. There is some refactoring of the Vim mock.
I updated the documentation and the contribution guidelines. I added a new instruction when creating an issue: adding the output of the `:YcmDebugInfo` command. We often ask it in the issues.
I suggest fetching the `ycm-toggle-logs` branch of my repository to test yourself this command.

If already opened logfiles are not visible (hidden buffers or in another
tab), close them and open new ones. It fixes the issue where the command
seems to do nothing even though it actually close the non-visible logfiles.
Mock buffers as a list of buffers where each buffer is represented
as a dictionary containing its filename, its number, and optionally
its associated window.
Test buffer visibility instead of existence.
Mock Vim wipeout command.
Refactor Vim mocks.
Run tests on OS X
There should be no difference between the behaviour on OS X and the behaviour on other platforms as all of the tests are python. However, running them is cheap and proves that there are no differences.
The approach is to import the scripts from `ycmd` with a couple of modifications:
- don't set `YCM_CORES=1` as we didn't before, and this makes the build a lot faster
- don't install `gcc-4.8` as we didn't before
- install `argparse` for the tests as it is not available in python2.6

Fix AppVeyor configuration
AppVeyor certainly made some changes to their infrastructures because the `run_tests.py` script is not properly executed anymore. We now need to specifically call it with python.
This is already done in the `ycmd` repository so no changes needed there.

Remove g:ycm_server_use_vim_stdout option
The `g:ycm_server_use_vim_stdout` option is not working like expected. ycmd logs are not written to the console when using the gui client with this option enabled. This is the case on Windows and I think @puremourning can confirm this on other platforms. Worse, it also makes the ycmd server unresponsive on Windows.
It's a big issue because we recommend to use this option in [CONTRIBUTING.md](https://github.com/Valloric/YouCompleteMe/blob/master/CONTRIBUTING.md).
This PR removes the option and updates the contribution guidelines by asking the user to put the `let g:ycm_server_keep_logfiles = 1` option instead.
To further improve the debugging process, I would like to add a new command `:YcmToggleLogs` (thanks to @puremourning for the idea) that automatically open or close the ycmd stdout and stderr logs as windows in Vim. If you agree, I'll send another PR adding the command.
Note: if you are wondering why the ycmd stdout logs are always empty while you are adding print statements in the ycmd code, this is because the output needs to be flushed: `sys.stdout.flush()`.

Add an entry for Fedora installation in README.md
Following PR #1740. Update the Vim documentation.
Maybe we should remove the `super-quick` in the titles to make them shorter and be consistent with the others. I'll update the PR if you agree.

Define Vim commands only if setup is successful
Vim commands (`YcmDebugInfo`, `YcmCompleter`, etc.) should not be defined if an error is encountered when processing the `s:SetUpPython` function. Why? Because those commands will return errors like `name 'ycm_state' is not defined`.
Note: due to an unexpected behavior, those commands work fine when libraries are found outdated. See issue #1726.

Fix rare crash when trying to jump to file which has .swp
One of my coworkers found this crash today. Usually he opens a lot of gvim-s and forgets about them, and eventually one of GoToDefinition commands backfired :)
