* Transcoder updates for validator warnings (gop, max-bitrates) for #50
* Make the variant settings easier to set/read in code
* Update test to reflect update to transcoder
* Reduce the buffer to give it a little more room to improve the quality. It feels a bit crunched right now.
* Fix test due to changed bitrate buffer ratios
* Tweak buffer size one more time to get errors in the validator to zero
* Saw errors w/ different bitrates, so tweaking it again
* New video transcoder
* Set a smaller max muxing size + logging tweaks
* No need to return an err since it wiill panic anyway
* Use a default encoder preset if one is not supplied
* Rename to NewTranscoder. Add comments.
* Rename Bitrate to VideoBitrate. Config file changes required with this rename.
* Allow overrides of segment length. Allow offline stream to live in a single segment
* Append offline state video to existin HLS stream instead of overwriting because players do not like that
* Make properties private as they do not need to be exported
