makefile fix: no need to check docker version any more
use pg in dev settings
got sick of subpages app

there's no actual need for this to be in the db cause nobody edits it for years
and it makes it harder to setup a local copy for developemnt, not to mention versioning
a bunch of media/uploads files. Subpages is no completely static, with nothing saved in the db.
media/uploads from repo for good
news should be the first thing to show up on the frontpage

followed by daytime events, followed by evening events
