pyclass should be a module
Currently we import from the pyclass dir as top-level imports. E.g. from nexus import NexusMod
. However, to be able to add, for example a git class for git-based mods that don't have any releases (tes3mp scripts for example commonly reside on git), we should change this to the form from pyclass.git import Git
to avoid conflicts (e.g. with GitPython).
