minor fixes

Filter out releases like `Louie.S02E11.PROOFFiX.720p.BluRay.x264-DEiMOS` and `Rome.S02.DiRFiXES.720p.BluRay.x264-SiNNERS` as they are useless for our purposes.

Remove `nl` from sub filtering as these releases are safe for english users and sometimes can only be found with them (1080p web-dl), thus the user can just disable the sub as the audio is in english.
