This takes the existing properties widget in the new material editor and
makes it reusable across multiple applications. It's now added to the
Armoury which shows the gear's used materials. It's also added to the
Data Explorer which now supports viewing material files.
I fixed the render viewport crashing when hiding it again, and made it
even more resilient.
Now the hashes are collected in a central database (location to be
improved) similar to FFXIV Explorer. This database needs to be generated
once and doesn't have to be regen every time Sagasu is opened like
before. This indexer currently is a separate program.
Also adds a feature to extract files from the file tree window.
