TextEditor: syntax color support.

Patch provided by Ricki Myers. Works quite obvious, see Theme editor too!

Notes about the provided code;
- The default syntax colors were screaming! Toned it down to match the
  default dark on lightgrey background better.
- Added: initializing colors in saved themes (usiblender.c)
- The implementation of the button for this option was quite clumsy...
  Blender UI options services this a lot easier.
  (Same fixed for 'line numbers' option)
- Bracket matching now uses as color a mix of backdrop and the
  selected-text color. Noticed my texteditor did it too...

-> I really miss comments in code describing a little bit the thought
   process behind the code. Like a short introduction on this feature
   in the top of the drawtext.c, little remarks on new functions.
   ALso in patch tracker or the mailinglist no docs was mentioned?

-> drawtext.c now gets messy quickly... lack of overview, structure,
   and confusing mix of personal coding styles.
   For not-active supported code dangerous...
