Xoom 3.8.3

This is a patch release.

Convenience types Action Type and Roster Get Candidates Policy were added to knowledge base, References Report and Bad References report.
The interpretation of ClickRoster configuration, generic events and reports were improved.
Corpus capture functionality was also improved. Among other things, Xoom Corpus Generator now captures more relevant information, which decreases the probability of missing the information required for the creation of custom Xoom installers.
