[Builder] Looking for testers for new JavaScript / TypeScript / JSX syntax highlighting

[Jeffery To <jeffery to gmail com>]

Hello!

I wrote new language definitions for TypeScript and JSX, and in the process rewrote the highlighting for _javascript_.

As these definitions are complex, I'm looking for users to help test and report bugs before submitting them to GtkSourceView.

The language definitions are available at:
https://github.com/jefferyto/gtksourceview-js-lang

Any help would be greatly appreciated - thanks!
