[For 1.6] Advanced Sidebox 2.1.1

[Destroy666]

A way to add multicolumn support in ASB's boxes without creating new tables inside shouldn't be hard - colspan="10" (so bigger than possible amount) on the thead <td> will do the thing, unless there is table-layout: fixed; enforced directly on each side box <table> (IIRC it was on main <table>, which won't disturb). It's a bit weird solution, but it works in all browsers, as I read, and is proper HTML.

Variables may not be accessible on all pages. Unless they're global, they won't work on other page just like on NewPoints list. You can try adding them to, for instance, forumdisplay template and they won't work there too - it's not Advanced Sidebox's fault.
