bigly changes (see description)

- use LdrRegisterDllNotification instead of LoadLibraryExW for patching
** LoadLibraryExW is currently still hooked for the UpdatePack7 compatibility fix, I'm looking into other alternatives
- more robust error checking
- refactored a lot of code to be more reusable
- header guards
- better logging framework
- tighter permissions on the unload event
- probably other stuff I forgot about
