Add ability to specify a default estate to be used when creating regions.

This is configured in the new [Estates] section of OpenSim.ini.
If a default estate is configured then all new regions are automatically joined to it instead of asking the user.
If the default estate does not already exist then it is created.
Current default behaviour remains the same - the user is asked for estate details when necessary.
Thanks to Frenando Oliveira for the patch which I adapated further.
