The "Cache-ing up to the competition" release

Unfortunately for the pun there isn't actually any competition to this software right now. However I did actually add a caching system, that part isn't a lie. Cache invalidates after 7 days, but that may be adjusted in the future.

This release also adds support for detection of when games are native to Linux, which helps display a more accurate representation of the Steam library.

Full Changelog: v1.0.2...v1.1.0
