Luna 0.7.0-rc7

Note: if there aren't any huge issues coming up with this version, it will be the last RC and the next release will not be marked as 'pre-release' anymore.

LUNA-69:

• disabling Eos telemetry should now work as expected

LUNA-70:

• removed OMDB scraper (doesn't provide game information anymore)
• removed IGDB scraper (changed their API)
• removed workaround to get cover arts from NVs GFE service (too many errors)
• if an error occurs for a certain game with a certain scraper, that scraper is now skipped (the error is still logged, however)

LUNA-71:

• using a mouse shouldn't throw a crazy amount of exceptions anymore

LUNA-72:

• added a readme section about Eos to clarify what it does and doesn't do
