Please reopen and fix IDEA-3692, allow plugin module to depend on plugin module

This issue is at http://jetbrains.net/jira/browse/IDEA-3692. It makes
developing any kind of modular plugin system very difficult. This is
probably the most important short-term request for me. Please make it
easy for plugins to depend on each other, instead of making me rm -rf
parts of plugins classes/ folders just to get it running right.

This should either be reopened/fixed or there should be some other means to support the
development of dependent plugins.
