Remove flask caching and unused imports

This removes Flask caching since it seems I'm dumb and can't implement
it correctly and it seems to serve pretty much no purpose anyway.
Caching can always be handled by the server in front

This commit also removes some unused imports that were leftover after
moving functionality to different files (like view_functions)

Flask compress might be useless too since nginx can also gzip. But I can
actually observe the change... is there any problem with double
gzipping?
