Turn the [RegionReady] module on by default and login_disable = true while scripts are loading.

From field experience, we know that simulators can be unstable if a user logs in before the scripts have finished loading.
This commit turns login_disable = true in [RegionReady] on by default which prevents this from happening.
If you want the old behaviour, please copy these section from OpenSimDefaults.ini into OpenSim.ini and set login_disable = false

bin/OpenSimDefaults.ini
