GH-206 Configureable 'tune' property for rtmp video encoding

'tune' property is now configureable, used to set the property in
x264enc (see http://mewiki.project357.com/wiki/X264_Settings).
Also added a note about setting other outputs to be leaky when
using rtmp.  As well, added connecting signal to video quality
spinbox that was missing
