Places the columns next to eachother instead of underneath

The 45% + 10% + 45% failed in IE7, making the 2nd column fall
underneath the first. This fixes that by changing the widths to 45% +
45% + [whatever is left].
Adds global state check for old IE (7) and makes clicking options work

Adds option (state) "isOldIE" which is set to true if $.browser is
present and checks positive for ie7.

Also makes clicking options work in ie7 (by replacing the click event
with mouseup event which is the bizar fix).

necessary on <li>s so it's now prevented.
