Implement /pseuco-ide and /pseuco-java-compiler

I was about to tear off the entire angular skeleton when I stumbled over these two (kind of) innocent pages.

The resulting pages look (almost) identical to their pseuco.com (AngularJS) equivalent and the changelog protocol of /pseuco-ide is working fine, too. Give or take some Nitpicks from @fefrei, this MR should be of little hassle.
