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
```
