Changed wxGTK dependency to 2.6 and made ebuild use wxwidgets eclass. Note
that this package ignores WX_* variables and just compiles against the
default wx flavour (ansi/unicode). This will need to be fixed after we get
better wx-config management. Added patch for GCC 4.1. The build was actually
failing but would not die for some reason, leaving half the package
uncompiled and installing the rest (!). Added -fno-strict-aliasing CFLAG.
Removed pythonhead from metadata.
