JIRA-GRails-2221: OSGI and GRails Integration

JIRA-Grails-2221: To implement grails plugin system based on OSGI

I think, for backward compatibility we should not  rerestruct  GRails.

We should develop plugin - grails-osgi-plugin or grails-felix-plugin or grails-equinox-plugin to support OSGi.


Now 1.2-SNAPSHOT will be released, but no OSGi support is avaible.

Should we rerestruct GRails to be wholly different from the old release?

Could we develop a plugin called grails-osgi or grails-felix or grails-equinox? Then we can make grails new release backward compatibility more easily. If we need a plugin depends on OSGi, we can install grails-osgi-plugin or grails-felix-plugin. If we do not need OSGi support, we can use old plugin system.

Modulization and plugins-support is somewhat different.

Any suggestions?
