#52 static methods in abstract classes

First off, this is an outstanding plugin - I've not seen anything like it until now.

However, it seems that calls to static methods in abstract classes are not detected.

This has a significant negative impact on the understanding of a system when dependencies on these methods is invisible, and one needs to dig into the actual lines of code.

Thanks for the comments.
I'll look into the static methods in abstract classes.
There hasn't been any work done on Creole recently, so no guarantees.
