SublimeText launched from GUI doesn't find ocamlmerlin

[rebeccacremona]

As mentioned in the SublimeREPL repo, "On POSIX system SublimeText launched from GUI does not inherit a proper environment. Often leading to problems with finding interpreters or not using the ones affected by changes in ~/.profile / *rc files".

Though this is a Sublime bug, it has the effect that Merlin often doesn't work for people who open their ml files using the Sublime GUI.... the ocamlmerlin binary often can't be found. The SublimeREPL folks have added a workaround to their plugin. It might be nice to do similar here.

Or, it might be worth documenting that users running into trouble when opening files from the GUI should manually set "ocamlmerlin_path" in their Merlin package user settings.
