Vala and Graphviz

Hello,
it's often useful for Vala hackers to have a graphical representation of the code tree and control flow blocks. Therefore I've created a simple application called Valag which generates four types of diagrams using Graphviz for each state of the Vala compiler.

This is the first release, there're many things to fix and enhance (like command line options) but it is working quite good already to give support when hacking Vala.
