"CompareSubtitle" rewrite to get the exactly srt file...

Rewrite of "CompareSubtitle" to get the exactly .srt file (if it exists) instead of renaming the "best"(sometimes wrong) subtitle with the video file name (old way). With this new code, it will search by video quality (1080p, 720p, 420p or just HDTV) and then will compare the srt files with video file using Release group and video quality. I found a bug with periscope that it won't download more than 1 items in the queue (LOG: writing 2 items to queue)- don't work and I don't know how to fix it. It will only download the first item. I found another bug that if there's two versions of the same tv show/episose (1080p and 720p for example) Periscope/script crash when trying to download them. If anyone can test it I would appreciate. This is my first attempt programming in python.
