RPCGecko v1.1

Yes, I actually tested my spaghetti code this time.

Changes from v1.0

• A bunch of new higher quality game icons have been added - see /assets
• Rich Presence assets are now referenced in their own icons.yml file
• titles.csv and icons.yml are automatically downloaded from the gh-pages branch if they don't exist locally
• Elapsed time in Discord now resets when the running title changes
• RPCGecko now shows brief descriptions for available updates

Bug fixes

• Rich Presence now disconnects properly when TCPGecko times out
• Reference to non-existent "CSV update" function in settings and config.yml has been removed (how did that end up there?)
• Some minor code changes for readability that don't affect functionality much

macOS and Linux users can run rpcgecko.py or build from source.
