Subject: [PATCH] texlab: 1.10.0 -> 2.0.0

Also added a configurable wrapper that puts a TeX Distribution into PATH.
Defaults to texlive.combined.scheme-small.

Without this wrapper, the following message is displayed on startup:
Your TeX distribution could not be detected. Please make sure that your distribution is in your PATH.
