Add a simple ContainedDep mechanic- mods can contain other mods or libs, and can specify them using a manifest tag: "ContainedDeps". 

This is a space separated (manifest standard) list of jar files that are to be extracted into the version specific directory.

There's also a special system property "fml.skipContainedDeps" that will allow for runtime skipping of extraction of contained deps (a comma separated list, based on the file name).
