Allow swizzling from database nodes #163
Description
Right now we can use James to call images up, and to swizzle images that we upload. Mixing those two features into a single command would safe a bit of time and scroll space.
For example, if I did "-swizzleimage archon", James could give me a list of results as normal, then swizzle the image found at that lookup choice. If a file is attached it should just override the lookup, as per how swizzling currently works.
