New video transcoder (#27)

Browse Source 
* 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
