Work Progress - Apr 6 - Apr 12

Demo: "SB in beta" link above

Work done:
* Fix "otherwise" of if...then...else...
* Reduce codelet size
* Better coloring scheme - property codelets now show as light purple block with black text
* Smoothing the lines and images of the graphics windows.
Before
After
* Enable speedup without sacrificing simulation accuracy - the trick is to increase the speedup factor in the advanced property tab of BoarderEngine and the steps parameter in the same tab in tandem, say changing them from (0.8, 1) to (1.6, 2). This will double the number of internal simulations done per frame.
