#5 Add HEVC/H.265 format support

[wincmd]

Hello!
I 've been using your player for years. I consider it the fastest optimal in speed, size, appearance and functionality (with rare exceptions). But there is a great lack of quality continuous (smooth, no jerks) operation of HEVC format video. Because of this, I have to use other players.
I kindly ask to add this possibility! :)
