[Boa Constr] last cvs bug

[Michele P. <mic...@un...>]

Hi,
the wx.Locale.IsAvailable was introduce into 2.7.1, so for old version,
use this function can be a problem. This patch solve the problem.
PrefsExplorer line 379

     def getValues(self):
         if wx.__version__ >= '2.7.1.0':
             return ['wx.'+n for n in dir(wx)
                 if n.startswith('LANGUAGE_') and 
wx.Locale.IsAvailable(getattr(wx, n))]
         else:
             return ['wx.'+n for n in dir(wx)
                 if n.startswith('LANGUAGE_') ]
