Updated Operations and Properties

- Updated Operations and Properties with tpying and logging.

I have not updated translation files, this is because i want to gut MMD Tools system and replace it with our own, however I want to make MMD Tools more simple and ajust it to our needs only. This is going to take a while and my aim for this is Alpha 4, also the MMD Translation system hurt my head....

- Fixes a couple of bugs as well, with quick access and the PMX importer.
