Make editable installs possible

[larsevj]

Issue Resolves #44

Approach Renames _komodo.pth to zzz_komodo.pth such that it is sorted after "most" other packages and as such gets added last to path, allowing other packages to "overwrite" with editable installs.

Also removes seemingly unused python types and python shims code.
