UpdateWrapper Syncing

[Dan-Nolan]

Currently the UpdateWrapper abstraction doesn't know how to properly sync outside changes. This should be updated if possible to handle specific edge cases.

Further explanation from #124:

There's an UpdateWrapper component that is a nice abstraction for all Builder components and ties in nicely to the Save/AutoSave flow. Unfortunately, it has a hard time with changes that come from outside the component. Currently the UpdateWrapper prioritizes its own changes and disregards those that come from above it. It doesn't know how to sync the changes in. Perhaps it could accept any incoming changes and automatically set that as its original state, that way we don't need further updates.

This is especially concerning when switching between branches on Github. It doesn't really show that the files have changed until I reload. We should really come up with a dialog to let the user know it's been changed from the outside.
