Merge branch '0.3.8' of https://github.com/RactiveJS/Ractive into 0.3.8
refactored tests, using qunit extension for html comparisons
made render() a prototype method, so it can be overridden by components if necessary
renamed parentNode -> pNode, for easier future refactoring (and smaller filesize!)
add test for #237 and #240
