replace System.out calls with logger calls
extracted validation methods out into separate utility class

later.
Merge remote-tracking branch 'origin/master' into useSQLSetupRules
Merge pull request #17 from ualerts-org/useSQLSetupRules

More use of SQL setup rules
changed default dialect to HSQL
set default hbm2ddl.auto mode to 'update'
changed scope of hsqldb dependency to compile
added context.xml with resource for default embedded database

added package-info.java
added embedded database server bean
refactored embedded database server to not require ServletContext
moved hsqldb dependency to service module, with compile scope
