[READY] Add client logfile
We have a lot of issue reports with Python exceptions that interrupt user workflow or even worse make the editor unusable and force users to restart it (e.g. issue https://github.com/Valloric/YouCompleteMe/issues/2192). We really want to avoid that but at the same time we can't just silence these exceptions because they are useful to debug the issue. Logging them to Vim `:messages` is not practical because we can't write to it without displaying messages in the status line which, in addition to distract users, may lead to various issues like the infamous `Press ENTER or type command to continue` message. This is why a logfile is needed.
For now, only server crashes are logged but more logging will be added: connection issues with the server (`ConnectTimeout`, `ReadTimeout`, etc. exceptions), UltiSnips unavailability, requests sent to the server, etc.
The behavior of the `:YcmToggleLogs` command is changed to accept multiple arguments where each argument is a logfile name. Each of these files is opened in a separate window or closed if already open. When no argument is given, the list of available logfiles is displayed to the user. Example:
```
Available logfiles are:
ycm_pz83u7.log
ycmd_23830_stderr_gf6j3i.log
ycmd_23830_stdout_gmpa_k.log
```
With this change and PR #2342, we will add the completers logfiles to the list of files that can be opened with the `:YcmToggleLogs` command.
A bunch of tests are added that cover almost all changes introduced by this PR.

[READY] Bumps required Vim to 7.4.143 and adopts TextChangedI.
Long and personal experience, when TextChangedI gets used, YCM seems
to perform better, diagnostics will trigger much less frequently at
inappropriate occasions, even less with whitespace agnostic triggers,
if I recall correctly...
There's a previous discussion at #1337. At the time this change was bundled in
a single pull request with other changes.
It has gone through the test of the time, sole issue I've stumbled upon was reported
by @puremourning at https://github.com/oblitum/YouCompleteMe/issues/10. This
is what me and other users of my fork use daily.

Open the quickfix window to full width at the bottom of the screen with
its height set to fit all entries. This behavior can be overridden by
using the YcmQuickFixOpened autocommand.
Add a new section for autocommands in the documentation.
Update GoTo and ReplaceChunks tests.
Add how to build python to avoid startup problems (in particular, pyenv)

# Why this change is necessary and useful
I spent a while trying to find where I had written the instructions for building python with pyenv to work with YCM, then I thought the README was a good place for it.
ycmd must use pythons with `--enable-shared` or `--enable-framework` else boom.

As requested in https://github.com/Valloric/YouCompleteMe/issues/2052#issuecomment-195631106 I'm sending this PR. I've marked it as WIP because I've renamed only the `ycmd` option and that is because keeping the backward compatibility here was straight forward since is a client only option. For the jedihttp option instead I would like some opinion on how to procede: should we keep the backward compatibility here on the client or should we make the backward compatibility layer on the ycmd side? Keeping it here would be easier but it would mean that other clients should implement this theirself. Thoughts?

[READY] Fix multiline title entry in FAQ
Apparently, it is not possible to write a header on multiple lines using the `#` syntax in markdown, so we write it on one line.
Update the vim docs too.

Make headings and TOC entries have the same text.
Use Title Case for TOC entries.
Add "Miscellaneous commands" and "Functions" entries.
Set "And That's not all..." heading in bold instead.
Move "Diagnostic highlighting groups" to a third-level entry.
Additionally, we restructure subcommands section to organise by
command type.
There are now a significant number of subcommands offering quite
powerful features. A flat-list of such commands is not easy for users to
discover (citation needed). Restructured into:
- GoTo commands
- Documenation/type information commands
- FixIt/refactor commands
This has the following benefits:
- features are more discoverable to the user (due to contents page
update)
- more obvious where to add new subcommand documentation
- a place to write notes which apply to multiple commands (such as
jump lists, multi-file refactor)
[READY] Update Go documentation with GoTo subcommands
This also updates to latest ycmd. Changes that affect the client:
- update racerd;
- add GoTo support for Go completer;
- add concurrent requests for Typescript completer;
- fix issue #1953;
- add GoToReferences support for Typescript completer.
I changed the filetypes lists to be in alphabetical order, except the C-family languages.

Update subcommmands supported for typescript
Noticed that the subcommands supported by typescript are not listed. Updated the docs and ran
```
vim-tools/html2vimdoc.py -f youcompleteme README.md > doc/youcompleteme.txt
