Fixed Quality Options missing

Stupid... little... bug... -.- This fixes like: #702 #685 #691
Version Bump -> 0.2.8.1

Hotfix for quality bug
For some reason, node-webkit-builder didn't update in the merge
Fixed package.json
Update README.md
Sped up subtitle requests

If all subtitles are cached we will no longer make a request to YSubs to get an 'empty' list of subtitles. Saves ~1000ms!
Speed up API requests!

XHR requests seem to be much, much, much faster in node-webkit than node requets. We use jQuery until things work again
