Changing "styles" to "render methods" so I can use "style" to refer to a persistent text appearance configuration. Unified some of the layout logic in Body.
Did a shitload of stuff, actually. Styles now work really well– though they haven't been tested on long strings. Thing is, UIBody is now gross. Also Styles got renamed to RenderMethods, because "style" typically connotes a higher level text transform. Did some more cleaning up too.
