Edited the transmission plugin so that it can handle transmission internal limits for seed ratio and idle time, they are applied by default on the input plugin when onlycomplete is true, and optional in transmission_clean with transmission_seeds_limits
renamed transmission_seeds_limits config key to transmission_seed_limits, corrected pathc to comply pep8
forgot to rename entry in option validator in transmission plugin
