Added script to UI bytecode compile + file browser

Browse Source 
This is quite a big commit which adds an experimental text script to
UI bytecode compiler. The compiler is still under heavy development
and can and will be under heavy changes, so use with caution.

In addition I added the old file browser for unix like platforms
back into the demo. At the moment it only supports windows but
the only part of the file browser that is platform dependend
is the directory content loader which should be easy to implement
in other platforms as well.
