- 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
