Added a simple means of detecting this inventory UI, such that another UI mod can easily detect it.
You can test for the path "/bk3k_reskin1_layout" (playerinventory.config) and if it exists, this mod is present.
Note that the 40, 60, and 180 slot patches now test for this path.

The path "/color_theme" was also added, and the value set to "black" although currently no other options exist. Not sure if that will ever be useful, but it exists.
