Amended PSR-2 to support tabs

Spaces
The final frontier... 
This now supports tabs in order to fix the Internet.

Now, in all seriousness, this should be merged in order to solve the complaints on tabs vs spaces.
There's one thing that it should be mentioned, there's no subversioning notice, release date/update date for the PSRs which might make updates such as this (hope it will never ever happen) noticeable by the users.

As always, the discussion is on THE MAILING LIST (look the website for it) and all comments here will be ignored.

Best regards.
