[SVN] r2174 (Python)

[Jeroen van der Ham]

• Added whitespace cleanup script (with small typo fix) from Jay Soffian. 
  This script will strip trailing whitespace, and put enough whitespace back on empty lines to fix folding.
• Enhanced symbolList match to exclude "def" and default values (based on Graeme Mathiesons transformation).
  This one should also show leading whitespace as soon as Allan enables that in the symbolList.

Changed:
