Vala support

[CoderThomasB]

Vala is a C# / Java like programming language that compiles to C. Vala supports things like namespaces and classes using the GObject library. Vala will use vAPI files to bind normal functions and structures in C libraries to be used in Cala.

It would be interesting to see if the two separate steps of compilation had a significant effect on performance. I have created a few apps using Vala and GTK on Linux but I don't really understand how the permissive works. So if anyone else has had experience with Vala, please comment or open a PR.
