Revert "Universal Storage"

Reverts KSP-CKAN/CKAN-meta#60

I'm undoing this merge for the following reasons:

- UniversalStorageCore appears to bundle USI Tools, when its should depend on it. (Right now, nobody can install US if they have any of RoverDude's mods installs)
- UniversalStorage should probably just be called `UniversalStorage`, since this is what players will want to install. (Usually `-core` is for a stripped down mod, like Firespitter-Core)
- Filenames should be `Modname-version.ckan`. I should instruct travis to check this for us.
- Neither the -TAC nor the -KAS version depend upon the core, but being a US user from long back I'm pretty sure they should.
- These would look prettier named `UnviersalStorage-KAS` and `UnivervrsalStorage-TAC` (minor nitpick, but almost all our other mods use `Base-Extension` as a naming scheme, so we should try to be consistent.)
