Start interacting with the IntelliJ Tooling API, by trying to inject the syntax colouring settings for xtc programmatically

[lagergren]

Right now there is an ugly-hack in bin, where you can run the script xtc2IDEA.sh (that only works on Mac), that copies bin/Ecstasy.xml, which is syntax highlighting settings and things like that over your local IntelliJ distribution.

This should be exactly what tooling api configuration is meant to do in IntelliJ, and we are going to need that entry point to implement a bridge to any language server implementation we are building that should work for IntelliJ.

So the feature request is investigate how to, and then implement, x syntax highlighting from the application of the xtc plugin to a project (or any entry point really), programmatically through supported APIs.
