config cache issues

By default the configuration cached by the mod_perl2 instance.
You can disable cache by setting cache/config=0.
You should disable cache only if you have multiple calcms instances
running on the same mod_perl2 server with different configuration.

The Location of the configuration will be determined by config module
now.
