- pass the svn revision as format version (for more detailed verification)
- add an 'autoreload' setting that makes Gridworks autoreload its self if a class gets changed (this is useful to make development cycles faster when working on the java code with autocompiling IDE like Eclipse or IDEA) git-svn-id: http://google-refine.googlecode.com/svn/trunk@372 7d457c2a-affb-35e4-300a-418c747d4874
