alphanumeric ordering of covers in library
Brought to you by:

Fixes library view in the same way as this patch (non-lexographic sort): https://sourceforge.net/tracker/?func=detail&aid=2811656&group_id=146377&atid=764987
I wasn't able to use the alphanumeric_sort() function, since it only operates on a list of strings. It so happens that LooseVersion from distutils peforms the same kind of sort (batteries are definitely included in Python!), so I used that instead.
apply with "patch -p0 < libary.py.patch" from trunk/
better patch (fixes both BookArea and CollectionArea)
