== Pynodes ==

1) Trying to bring back compatibility with Python2.3.
2) Adding some stubs to compile blender player again on linux.

Please tell me if Blender still doesn't compile with py 2.3 or if the player isn't compiling. There was a binreloc related stub I needed to add, so probably the player wasn't compiling before the pynodes commit.

Thanks PanzerMKZ for reporting and testing part of the fix to py 2.3.
