ExtensionRepository refactoring

[clarkwinkelmann]

Refactored the ExtensionRepository into 3 classes:

• The actual repository, which holds extension logic used in Bazaar
• The cache repository, responsible of saving and updating the data from flagrow.io
• The extension factory, which does the assembly of the flagrow.io data and the extension manager data

Also renamed a bunch of variables in ExtensionRepository, their naming was very confusing.

There are probably still improvements to do. But I think it's already a lot cleaner.

It's now possible to update only part of the cache. It's used for the favorite feature and I plan to use it for premium extension state as well in #66

By the way, this fixes #76 by completely removing the old code that used it.
