Moved the test-servlet-context configuration to src/test/resources.
Moved the test database settings from the test Spring config to a
properties file.
Added hsqldb maven dependency and settings in test.database.properties.
Corrected the hibernate.dialect property's value.
Added configurations for in-memory Hypersonic SQL database (hsqldb).
Replaced JSONSimple in the RestController with Gson, as Gson is type
safe.  Added -Xlint:unchecked as a compiler argument.
Replaced typeahead.js with jQuery autocomplete because autocomplete
allows easier matches on substrings.
Removed 'return false' from the select function so that other keys
aren't disabled and instead perform their default actions.
Updated .gitignore for IntelliJ.
Added a database properties file to remove hard-coded properties from the servlet configuration.
