Having a gitignore-everything ("*") file within a flask session folder seems to cause a
weird bug where the state of the app becomes unusable from continuously
trying to prune files listed in the gitignore (and it can't prune '*').
- Switches from pycurl to requests library
- Allows for less janky decoding, especially with non-latin character
sets
- Adds session level management of user configs
- Allows for each session to set its own config (people are probably
going to complain about this, though not sure if it'll be the same
number of people who are upset that their friends/family have to share
their config)
- Updates key gen/regen to more aggressively swap out keys after each
request
