Bug#699352: please update to 1.7R4

[Thomas Koch]

The git repo of rhino is now at
http://git.debian.org/?p=pkg-java/rhino.git

I've merged upstreams 1.7R4 tag from github. Upstream now just links to the 
tag download link of github instead of uploading a tarball somewhere. Therefor 
I've not imported anything to pristine-tar for 1.7R4.

The thing even builds! Please have a look, test and probably upload to 
experimental. I'll test whether I can build closure-compiler against 1.7R4.
