[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] 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.
