Fastmenu update

Fastmenu is now a variable menu speed setting instead of an on/off toggle. This update reflects that and gives the player a lot of options for the particular setting (normal, instant, double, triple, quadruple, half). A smaller change in this update is removing quickswap and fastmenu from the output file name of the randomizer (reflective of how the adjuster allows them to be shifted freely anyway) and shortening the verbiage for when progressive settings are changed (quality of life change there).
