upgrade to grails 2.3.4

upgraded to the latest grails and related plugins
upgraded wrapper
fixed some code that no longer worked to get unit
tests to pass
upgrade illiad to 2.3.4

upgraded illiad to 2.3.4, but had to add spring-test directly via
BuildConfig.  Not really sure why this was required.  Also upgraded
the wrapper.
upgrade rid to grails 2.3.4

added new wrapper
set application.properties to 2.3.4

cleaned up Config.groovy in multiple projects, lots of logic that is
no longer used, like adding new drivers and what not

fixed buildconfig for illiad, it was not forking its execution

fixed some bootstrap inserts in rid, apparantly grails 2.3.4 converts
 all empty strings to null by default.  This can be turned off,
 but I would rather use grails 2.3.4 correctly
