[READY] Allow completion in the command-line window
This implements @puremourning's suggestion from https://github.com/Valloric/YouCompleteMe/pull/1415#issuecomment-460197058 and adds an entry in the FAQ on how to override the `TAB` mapping in the command-line window. Since the `CmdwinEnter` event is triggered instead of `BufEnter` in that window, the `s:OnBufferEnter` function is called for that event too. Also, the contents of that window are empty when the filetype is set the first time so we ignore the `FileType` event in that window. Finally, the `qf` filetype is removed from the `g:ycm_filetype_blacklist` option since the quickfix window is always ignored.
This needs testing as these changes may not work well with plugins that create special buffers. We may have to blacklist the filetype of these buffers.

# Why this change is necessary and useful
- The original installation guide missed `go build` in `godef`'s directory, relating issue [here](https://github.com/Valloric/YouCompleteMe/issues/3071#issuecomment-403213723).
- The path of `gocode` and `godef` has been changed, update them in the doc.
I have tested this guide on my Manjaro laptop and it works fine, my go version is `1.11.4`.
(Since the path is too long, the vim help doc looks kind of ugly, maybe the formatting or the
path's presenting way should be changed so that it looks better. I used the `gq` command
in vim and it gave me this.)

# Why this change is necessary and useful
clangd-based completer has been introduced into ycmd for a while now. I believe it is time to let users know about it as well. We are also updating clangd's docs and it would be nice to point people using vim into YCM docs for integration. You can see the patch for that one in https://reviews.llvm.org/D56718.
Also you can have a look at the end product of the changes at https://kadircet.github.io/YouCompleteMe

[READY] Ignore ft= argument from YcmCompleter command
The `ft=` argument of the `YcmCompleter` command is supposed to allow users to specify a completer when running a command. However, this was broken a long time ago in commit 29bb90a6b4. Only the `ycm:ident` value is still supported but it serves no purpose because the identifier completer doesn't define commands. Ignore completely the `ft=` argument and move the logic to the Python layer. Remove the argument from the documentation.

Only the "ycm:ident" value of the ft= argument in the YcmCompleter
command is working. This value forces the use of the identifier
completer which serve no purpose because this completer doesn't define
commands. Ignore completely the ft= argument and move the logic to the
Python layer.
[READY] Update Python documentation and add extra conf file
This PR updates the Python docs and adds a `.ycm_extra_conf.py` file to be able to complete third-party packages in YCM code.

[READY] Support modifiers for GoTo commands
This PR allows users to customize how a window is split when running the `GoTo*` commands by prefixing them with the modifiers `:aboveleft`, `:belowright`, `:botright`, etc. (see `:h mods` for the complete list). For instance, to split a window vertically at the right of the screen, one could do:
```viml
:botright vertical YcmCompleter GoTo
```
The `'horizontal-split'` and `'vertical-split'` values of the `g:ycm_goto_buffer_command` option are replaced by `'split'` since a vertical split can be obtained by prefixing the `:vertical` modifier. Those values are still kept for backward compatibility.
A new value is added `'split-or-existing-window'` that is equivalent to `new-or-existing-tab` when the `:tab` modifier is used. Without the `:tab` modifier, the `GoTo*` commands only jump to an existing window if that window is in the current tab page.
Closes https://github.com/Valloric/YouCompleteMe/pull/3090.

Since the latest anaconda works with YCM, let's just state that it is not supported in the README.
[Please explain **in detail** why the changes in this PR are needed.]
