1.1-rc1

contains the latest changes to authorization framework, mainly targeting authorization stacks to groups/projects

Note that full reindex is not necessary however one incremental run of indexer is needed because the format of configuration changed (namely projects are stored in a Map as opposed to List) so it needs to be regenerated by the indexer and written down to configuration.xml.

Also, note that EXUBERANT_CTAGS environment variable changed to OPENGROK_CTAGS.
