Mule 3.4.0 Posgtres 9.3  Properties for production

@bpeng - please give @quiffman a chance to review before merging.

* Update to Postgres 9.3 Mule 3.4.0
* Remove the IDP receiver (small chance of it causing errors).
* Improve property setting for production.

I tried to update AMQ but ran into issues https://github.com/GeoNet/mule-quake-db-client/issues/16

@quiffman - despite what the docs say I couldn't get this to read context properties from a file:/// _and_ start the app in the Mule server.  Not ideal...  However, the $MULE_HOME/conf solution is fine - see the README.  This appears on the classpath after the one in the app zip file and does override.

The Mule server (3.4.0) should not need any intervention to configure it for the application now (asides from central syslog) and the properties shouldn't show in ps.

@pedrorgirardi - you asked :-)
