Add user preference to disable/enable bunny-hopping

title

certain platforming-intense maps can be quite annoying to play with this feature active, as accidentally holding space can sometimes send you careening off an edge when normally it wouldn't do so

having it as a preference you can simply toggle would be really nice to have for scenarios like that, or for the rare person who simply doesn't want to use bunnyhops. also just generally a nice QoL thing
