Title: Adding source ruleset line numbers support for debugging purposes.

Hi,

I am WebKit Web Inspector / Chrome Developer Tools developer.
We have just added an experimental SASS support.
It is based on source mappings generated by sass when run with --line-numbers command line flag.
I'd like to add similar functionality to LESS.
Could you please review these changes?
