Equation Editor 2.8 breaks up

Hi, All changes except (6) gave been implemented. I've all spaced out the operator drop down panel and added in a few extra buttons (just because there was space).

The insertion of text should now also be more logicial, particularly when you have text selected.

I've also made the rehearsal the final! Please make sure you refresh your browsers.

I'm aware of one bug which I haven't yet fixed. In theory it shouldn't matter, however Firefox and IE will log it as an error and you might see a debug box appear in IE if you have debugging turning on. Will resolve this once I remember how to write regular-expressions!
