LSL support

[nemurimasu]

I've created a syntax mode for Linden Scripting Language based on C/C++ mode and the LSL Wiki as of 2013-01-27.

This is my first time making a syntax module for Ace. Let me know if I've done anything wrong.

Looks good. I'd be happy to merge but unfortunately we had to restore requirement for CLA,
so i have to ask, can you send one to [email protected] please. See https://github.com/ajaxorg/ace/blob/master/CONTRIBUTING.md for details.

I would like to remain fairly anonymous. I have a crazy plan to make something really cool (if I manage to work on it enough) but I'm afraid to link this identity to myself because I don't want to deal with people thinking I'm weird. I don't need to see this merged into the main Ace repository but thought it could be nice for somebody.

Ok, looks like in rare cases we can add modes without a cla since they are selfcontained, and do not affect the rest of the code (can be removed or replaced if needed). But majority of ace users don't care about cla so this is still useful.
Thanks for the pr, it's already something really cool!
