Added support to run WISE with HSQLDB. This required being able to specify more hibernate options in portal[_sample].properties and changing some queries that assumed MySQL to work with SQL. Also created import.sql file which contains initial data that will be read-in by WISE when it's in HSQLDB mode.
Upgraded Spring from 3.0.5 to 3.2.3. Cleaned up pom.xml file and upgraded other minor dependencies' versions.
