[feature] highlight function definitions/calls in a different color than atoms

[SpaceOgre]

It would increase readability of code if it was possible to have function calls and definitions highlighted in a different color than atoms. I know that it's not a high priority feature but it would certainly make my life easier :)

Hi! This is quite difficult with the current implementation, but soon (hopefully in september) we will release a new one that will allow such things and more.

The implementation I mentioned above proved to have performance problems, we are on another track...
