+ Cache is no longer contained in app structure
This should let us later throw this into an Arc<Mutex<>> for better
async support.
! Also more cache access safety is being done on the front end because the cahe doesn't guarantee much on access
Perhaps some convenience wrappers would make this look nicer(with inline)
!!! Main needs a lot of flattening
It's technically not much of a problem since most of the code behind 1/2 match's
which really just bloat the hell out of indentation making it look bad when its not _that_ bad.
However it still bugs me so I should probably do something about that(also (inline))
