At the moment it is not possible to use skin layers in pure python
packages. This is caused by the DirectoryView implementation using
a minimal path name for the layer id. This path name is created
by CMFCore.utils.minimalpath, which uses the ProductsPaths list of
directories to look for the filesystem directory and uses an absolute
path if it can't find it. Since this absolute path will differ per
install you can't use it in something like genericsetup profiles.

The patch below fixes this by adding $INSTANCE_HOME/lib/python to the
ProductsPaths list. This allows minimalpath to find python packages installed

Are there any objections to commiting this to trunk?
