Base now supports database registrations which are declared as read-only.
Database registrations are normally maintained via
Tools/Options/Databases. The registrations are stored in
OpenOffice.org's configuration, which means it is also possible to
deploy additional configuration fragments (e.g. via extensions) which
contain additional registrations. If those configuration fragments are
declared as read-only (by using the usual configuration mechanisms for
this), then the UI now respects this, by disallowing modifications
(editions, removal) of this registration entry.
