[patch] updated syntax file for DataScript (*.ds)

[Dominique Pellé]

Hi

Attached patch improves syntax highlighting for DataScript files:
- better synchronization to fix highlighting when scrolling back
- use doxygen syntax for DataScript files (as for C, C++, C#, IDL, java, php)
- added a few keywords
- fixed obsolete URL

Regards
Dominique
