libtext & mod_text in

I've integrated libtext and mod_text. This means that you can now use write, write_var and similar functions.
The test code sets the text color to red, and moves it when you press the right mouse button. Then deletes it. Seems to be working pretty well.

Things are starting to come up nicely so if you want to give it a try, I've uploaded new binaries to the google code page for you to give'em a try.
