Changed the criteria API into a 'fluent' style API for setters. Added array
support to the InRestriction.
Unused import cleanup.
Lint cleanup.
Moved some code over from using the Hibernate-specific OnmsCriteria class to the
new Criteria class. Isolated the deprecated OnmsCriteria functions inside a new
LegacyOnmsDao interface. Most of the remaining OnmsCriteria code is inside the web
UI code.
