Run 'safe' 2to3 fixers and convert print to PtDebugPrint

[ghost]

Run those 2to3 fixers which should be safe. Additionally, change print calls to PtDebugPrint.

Included fixers: print, exec, import, has_key, repr, funcattrs, raise, except.

Excluded fixers and reasons. Links to commits which apply the fix.

• unicode: scary string handling changes
• dict, xrange: changes behaviour (list vs generators) so should only happen when switching to py3. Also generators should be introduced in the py2 code.
• imports: changes cPickle to pickle which in py2 is a speed difference.
• long: scary type handling changes
• metaclass: creates non-py2 code.

The system/ directory is excluded from changes.

Conflixed!

I think you need to make a pass through and look for any commented out print statements that may be lurking around. I saw a few just glancing at the changes.

Also, there are a few files where it would make more sense to not convert the print() function calls to PtDebugPrint():

• xEnum.py
  The prints are in a test block that will probably be executed outside of the engine. Hence, PtDebugPrint() is just a stub.
• plasma/pch.py
  This is designed to be used as console helpers, so we expect the output to be redirected to the console (I hope...). Using PtDebugPrint() sends the output to the log instead.
• xCheat.py
  This file is used by the Python.Cheat console command and, as above, should output to the console, not the log. Further, xCheat tends to import Plasma instead of from Plasma import *, so the proper call in this file would be plasma.PtDebugPrint() -- not PtDebugPrint().

2to3 ignores comments, hence they were skipped (it might affect other fixers as well). I've done a search-replace for the commented prints and amended the commit with those. I also reverted the ones in the three files you mentioned.
