hp-plugin needs /usr/bin/python to point to python3*

[Leo Milano]

After upgrading to Vivid, my HP LaserJet M1212nf MFP would not work anymore, and trying to install the binary driver, as prompted by the HPLIP utility would fail. After fiddling for a good hour, I realized that the utility was failing to load the python modules for hplip:

####
$ gksu hp-plugin

Uncompressing HPLIP 3.15.2 Plugin Self Extracting Archive...............................
Error importing HPLIP modules. Is HPLIP installed?
####

I changed to /usr/bin, and noticed that python was a symlink to python2.7; I temporarily made it be a symlink to python3.4, and I managed to install the proprietary plugin for my printer. However, other software would crash, so I reverted to have the symlink pointing to the old python2.7 location.
