Adds steam family sharing support to the Galaxy GOG 2 steam integration plugin
My pull request got rejected because of understandable reasons. I can't stand not having those sweet games on GOG 2 so I remade it into something easier to maintain. This needs manual patching unfortunately.
INSTALLATION STEPS
a) Close GOG Galaxy
b) Place pluginsharing.py into: %localappdata%\GOG.com\Galaxy\plugins\installed\steam_ca27391f-2675-49b1-92c0-896d43afa4f8
c) Edit the manifest.json in that folder and replace plugin.py with pluginsharing.py in the last line
d) Open steam client and add a nickname to each of your friends that are sharing games with you so that it ends with # example: Turn Nick1234 into Nick1234# or something similar
e) Open GOG Galaxy
