New syntax highlighter not complete.

- Supports comments
- more efficient as it scans the text block instead of repeatedly searching throught the whole block
- type matching based on catalog (but need to add aliases manually)
- added many keywords

todo:
- heap corruption bug
- symbol stops at special char like parenthese or operator or something similar.
