From: Dr Scofield <DrScofield@xyzzyxyzzy.net>

the attached patch set adds the (still work-in-progress but already
working) RestPlugin base class and the RestRegionPlugin code. we are using
XML serialization.

currently working:

GET /admin/regions/                 -> returns UUID list of known regions
   GET /admin/regions/<UUID>    -> returns detailed region information

we'll be adding support for POST/DELETE/PUT and also for
/admin/regions/<UUID>/name etc.
