Fixes #86

PR Type

What kind of change does this PR introduce?

• Feature

What is the current behavior?

Currently the roaming settings work is located in the UWP directory, making it only usable in UWP apps. It is also based on the older ObjectStorage interfaces in WCT, which are being deprecated in the near future.

What is the new behavior?

The roaming settings helpers have been majorly refactored and most importantly simplified! The new code is much easier to work with in my opinion, but it is also segmented a little differently.

Old, removed ❌
