plugin zips shouldn't be in source control
plugin.xml shouldn't be in source control
deleted unused files
cleanup
added new required properties: documentation, license, developers, issueManagement, url, scm
added BuildConfig.groovy with release plugin and Hibernate dependencies; it's not possible to depend on the Hibernate plugin because that will cause issues in the application, instead just added the same dependencies that the plugin will have regardless of its version
updated ancient project files
updated to Grails version 2.0.4 - use whatever 2.x version you like, but you must use 2.x to release plugins
