Based on issue #10 here is a fix to leave the .openshift directory

Based on issue issues #10 (https://github.com/smarterclayton/openshift-go-cart/issues/10) can you look at merging this in to the main repo as I cant see it affecting any of the standard operation of the cartridge but will allow people to run cron jobs.
Shouldn't this just be rm -rf $GOPATH?
