Make mastofe work like all the other frontends
This came up in pleroma!2400 (comment 65212). It would be nice if mastofe could work like the other frontends, live on / and be able to log in etc. Rebasing it to / is probably easy, but adding the basics for log in seems harder. Maybe we can pull in some stuff from @alexgleason's soapbox?
