fixes #175 - ractive.update() causes unresolved references corresponding to new properties to resolve
fix bug with indirect updates where the cache does not reflect reality
define Ractive.isFullscreen even if fullscreen is disabled (always returns false)
allow expression functions to be used in multiple instances of the same subclass with the correct context
improvements to components - camel case component names when translating template -> js, and dont lowercase attribute names
rebuilt
