Working on parsing UC metadata
Adding code to parse update center metadata.

The goal is to add a mode where plugins are uploaded from local computer to speed up testing
added code that uploads plugins instead of downloading it from community UC.

The hope is that this would take a lot less time, but right
now Aether seems to be taking a lot of time to start up
Switching to Eclipse Aether as opposed to embedding the whole Plexus.

This runs a whole lot faster.
