Title: Add colspan support to tablesorter

I added colspan support to your tablesorter version.

Given a table like this:

Colour Name	Colour Components

Red	Green	Blue

Pure Red	FF	00	00

Pure Green	00	FF	00

Pure Blue	00	00	FF

Orange	FF	A5	00

It will work as expected by clicking on "Colour Name" and "Red", "Green", "Blue".
Clicking on "Colour Components" will sort by "Red", then "Green" and finally "Blue".

Consider including this pull request if you want.

Part of the implementation is from [stackoverflow](http://stackoverflow.com/questions/2035056/tablesorter-2-0-3-colspan-issue). I extended it and I programmed the detectColspan function.
