Install Python version which is NOT available as system package

Did this on Server rose.inf.unibz.it ticket: #9012

download source code from https://www.python.org/downloads/
unpack: tar xfvJ python2.7.13.tar.xz
cd python2.7.13; mkdir /usr/local/python2713; ./configure –prefix=/usr/local/python2713
make
checkinstall (generates a *.deb file and installs it. Make sure you name it python2.7.13 otherwise it collides with existing system package!)
