#112 work

still needs to check if user has already skipped(not that they would be
able to vote doubly - but just to disable the vote button)
as well as doing the actual playlist skip
as well as updating the skip part of the interface on video change
as well as resetting skips on video pre-change(backend, regular TRUNCATE
TABLE maybe?)
#115 but that's the point of the branch idk
center on natural next play, too..
Merge pull request #137 from TeamSynergy/contrived-shit

skip system almost there
