Version checking

Hello Werner,

try:
   import wx.__version__ as version
   wxVersion = int(version[2])
   from wxPython.wx import *
   del version
except:
   import wxPython.__version__ as version
   wxVersion = int(version[2])
   import wx
   del version

I don't think this first part could be done in a nicer way... but probably
someone else will soon correct me and find an alternative solution.
Regarding the second part, wouldn't be so incorrect simply to use the tuple
object ability, like:

wx.VERSION > (2,5,0,0,"")

In my examples, it always works.

Sorry if this does not help so much...

Andrea.
