adding "welcome" support to Concierge: allows to specify via

       welcomes = /path/to/welcome/files/directory

a directory in which you can place welcome templates for concierged
regions (those regions that match the "regions" regexp). you can use
format substitution:

       0: will be replaced by avatar name of the avatar entering the region
       1: will be replaced by region name
       2: will be replaced the name of the concierge
