A few changes from the imr project:

* conf/scripts/config-script.sh: set client-min-messages through -c to avoid notifications.
The old method uses an option not supported by the cygwin client.

* kill-fcgi.sh: Use bash instead of sh to enjoy a few benefits.

* scripts/initdb.sh: Warn when the exported SQL file is not found for processing.
Changes to make the test program compile and run under Windows.

Since we have no GConf here, an abstract Config class was declared, that hides a GConf implementation (for Linux) and a ConfigurationManager implementation (for Windows). The ConfigurationManager implementation needs to be finished, it's a stub for now.
Ignore Debug/Release directories.
