NifSkope 1.1.3 / 2.0.0 Alpha 6

Correct Flags for BSXFlags, NiAVObject (Nodes and Shapes):
The flags for NiAVObject (NiNode, *TriShape, etc.) were severely out of date and I decoded their actual values. The same goes for BSXFlags which didn't have all the options listed.
(Note: Just because the options are there to check doesn't mean you should. :) The last 8 bits of the NiAVObject flags are not even supposed to be read from the file, and for BSXFlags there are several more options past what I've shown, but I believe they are runtime-only)
Major memory leak fixes:
There was a shameful number of memory leaks, most of which predated my involvement with the program. The number was so high that it made it hard for me to find the ones that mattered. After actually sitting down and attempting to fix them, I've managed to eliminate every leak I could find during normal usage.
Memory that wasn't leaking was also reduced slightly, and I will be focusing on usage more in future releases.

Material files (BGSM/BGEM) will no longer crash NifSkope if they are in JSON format. Note: They will still not be read if in JSON format.
Fixed several bugs caused by the partial data model refactor.
