upgraded to grails 2.2.3
fixed an issue in the buildWar closure of the Lightweight script that wrote the war to the wrong location in grails 2.2.3. This is a backwards compatible change.
bumped version to 0.8.1 (from 0.8.0)
reverted a typo I added to the plugin's 'issueManagement' metadata
Merge pull request #5 from bensfromoz/master
