updated to TideSDK and added lineDebuging output

Hey this is a super cool project. I really needed line debugging as a team I'm working with will be using LESS.

The changes include:
 - converting project to use TideSDK the new name of the previous Titanium desktop.
 - added LineDebug feature, per new feature of LESS, will out put line numbers pointing to original file.
 - upgraded LESS compiler to 1.3.3

For the time being i've put the distributable up https://github.com/krismeister/SimpLESS so people don't have to compile.

Tell me if theres anyway I can help out.
