Added Slider Update method, reworking of how Text Elements wrap (risky change), rework how MsgBox wraps 

Some risky changes to how text wraps, but hopefully these will fix problems of forms being way too wide.

Also added Update to Slider Element.  This allows it to be used for things like tracking progress in a song being played.
