Classic branch

Cleaned up the demos for ya. They should work with updated wx classic 2.8 - 2.9 and possibly further back to versions from old days they where originally wrote for. Some will work on Phoenix also. And basic preps for python 3 has been done. Ex: print('with parenthesis'). Also tried to trim trailing whitespace in all files.

Removed all the interpreter numbers from the shebangs. They were preventing users from attempting to run just because Ex: py24 or 25 wasn't installed. Also it is easier for the user to add interpreter numbers to the file shebang themselves when needed.

Basic pep8'd a lot of stuff for readability. Not the 79 chars per line style tho.
