Title: Basic Javascript language support: inline variable rename, inline error highlighting

This pull request adds:

* Generic infrastructure that extension can plug into that want to add analyses/parsers etc. for specific languages
* An extension that does parsing, variable instance highlighting and variable inline renaming, and emits warnings for unused variables and assigning to undeclared variables.

It also adds treehugger as a dependency.

Will walk through this with @sergi
