LegendKeeper 0.15.4.0

Images no longer need a "processing step" to be used as maps. You can instantly use any image as a map.
The distinction between images and map images in the Asset Manager has been removed. Everything is an image now, and an image can be used anywhere: as a map, as a cover image, as a banner, as an image block, etc.
Very large images that would take a while to load in their entirety now automatically preview using the tiling image viewer.
Fixed a bug that sometimes caused copy-pasted images in the editor not to be re-hosted on the LegendKeeper assets server.
Hotlinking images from other sites probably won't work at all now; be sure to rehost your images on LegendKeeper. LK will do its best to automate as much of this as possible.
I've replaced the image pipeline for LegendKeeper, which should result in more predictable behavior (once I iron out a few kinks.).
