[aur-general] kdebindings-python provides bindings for Python 3.x

Hi all, I updated kdebindings-python to provides bindings for Python 3.x. Many projects still use python 2.x so, we'll keep a new kdebindings-python2 package in our repo. We already rebuilt our packages, please maintainers update your packages on AUR.

From now on, /usr/bin/pykdeuic4 will refer to the python3 version.

/usr/bin/python2-pykdeuic4 will refer to the python2 version. Also, all examples and sip files, for the Python2 version, are stored respectively in /usr/share/apps/pykde4/python2-examples and /usr/share/sip/python2-PyKDE4 Thanks. -- Andrea
