Greg Hurrell 1e3b7bae51 Don't use VimEnter initialization except when stating gui
This is another attempt at:

https://github.com/Valloric/YouCompleteMe/pull/2473

Which removed the apparently flawed attempt at "lazy" loading of YCM.
While it fails to get the load out of the critical startup path, it
*does* serve the useful purpose when starting up gvim of avoiding a
deadlock situation in gvim.

So, this time, we keep VimEnter, but only for the gui-starting case. We
update the comment to explain what is actually happening. And we can
keep the docs about how to defer loading.
