method documentation, and (b) correct.

merged adaptors removed and more docs added. load_registry_with_web_adaptors deprecated as new web does not allow this to work anymore, but Use load_registry_from_db can now be used instead

pretty much a rewrite of the sub get_all_adaptors. Now takes the optional species, group and type pairs. The adaptors are returned instantiated now.

species and group deprecatied. As these should not be used now that dbc is not part of the dbadaptor anymore.

Bug fix correcting sorting of transcript display_xrefs (originally between v1.83-1.84) had been reverted somehow. Re-instated.

subroutine clear, now added which will drop all database connections and reset the registry.  NOTE: if you load_all and the registry is loaded the subroutine clear is now automatically called first to clear out the old configuration before loading the new one.
