1.7.x

Hi Alex

We've done little work on the sass and bourbon sass processor.  We've found upgrading to jruby 1.7.6 speeds up the processing.

I've had to add the maven repository http://mvnrepository.com/ to be able to get the jruby-stdlib 1.7.6 artifact as it's not available in maven central.  I hope that's OK.

I've also partially fixed one of the tests you had to @Ignore, it now works when run from wro4j-extentions module, but not when run from the parent wro4j project.

Cheers

Simon
