Camembert IDE Go / Golang support

I have added more and more language support to Camembert to the point that now I use to edit and work
on just about all projects (Fantom, Go, Python, Ruby etc...).

Lately I've done quite a bit of code in GO at Rivet and Sway lately, so I've beefed up a bit the Go support in Camembert.

Here are some of the current features:

• Syntax highlighting.

• Build/Test/Run commands.

• Integrated documentation pane with search (godoc).

• Run/build output goes to console and error can be cliked to go directly to source location.

• Navigation panel: Shows structs, functions and vars with "hot links".

• GoFmt support can be called manually or automatically when .go files are saved.

• and probably more stuff I'm not thinking about right now ...
