YUI Compressor needed in classpath.

I'm blowing you up today as I'm trying to get this Anchor Tab production server running. :P

Looks like YUI isn't in the classpath, and thus compressing anything won't work, unless you manually add it using `project/build.sbt`. My suspicion is that this could be fixed by making it a libraryDependency in sbt-resource-management's `build.sbt` file.

I don't want to write, submit, and test a patch right now (I *am* still trying to get this server up), but if you agree I can do so at some point in the near future.
