[aur-requests] [PRQ#24224] Merge Request for gtk3-mushrooms

jonathon [1] filed a request to merge gtk3-mushrooms [2] into gtk3-classic [3]: Upstream -mushrooms is no longer maintained. I've been keeping -classic alive with refreshed patches, and after some discussion (https://github.com/krumelmonster/gtk3-mushrooms/issues/30) we decided that merging would be a good idea.
