Hi,
  I found that if you have multiple versions of wxPython (2.8 and 3.0)
installed and
enabled WX_PYTOHN_SCRIPTING macro, the wxPyCoreAPI_IMPORT call will
select the default one (in my case 2.8), and it will SEGV.

This because it does an import of wx._core_ and in my case is 2.8. (Ubuntu
14.04)

The patch calls wxversion.select() method to select 3.0 version before
wxCoreAPI_IMPORT call.

Cheers,
  Francesco
