Save properly edition

Changing how and where the item saves are made, was always going to cause me to miss something.

because we added the ability to batch save items, we missed a few areas on second passes where saves should have but now didn't happen.

fixes:
#20 Compositions not imported
#21 Media serialization fails because of unknown type.

features
#22 uSync dashboard isn't a dashboard anymore its part of the settings tree.
#22 we've added the ability to add expansions to usync - this is how snapshots, etc will be incorporated into the main usync package.
