[Dbix-class] ANNOUNCE: DBIx::Class 0.08112 released

[Peter Rabbitson]

A boring maintenance release, addressing a number of bugs and
regressions.

        - Remove the recommends from Makefile.PL, DBIx::Class is not
          supposed to have optional dependencies. ever.
        - Mangle the DBIx/Class.pm POD to be more clear about
          copyright and license
        - Put back PG's multiple autoinc per table support, accidentally
          dropped during the serial-autodetection rewrite
        - Make sure ResultSetColumn does not depend on the (undefined)
          return value of ->cursor->reset()
        - Add single() to ResultSetColumn (same semantics as ResultSet)
        - Make sure to turn off IDENTITY_INSERT after insert() on MSSQL
          tables that needed it
        - More informative exception on failing _resolve_relationship
        - Allow undef/NULL as the sole grouping value in Ordered
        - Fix unreported rollback exceptions in TxnScopeGuard
        - Fix overly-eager left-join chain enforcing code
        - Warn about using distinct with an existing group_by
        - Warn about attempting to $rs->get_column a non-unique column
          when has_many joins are added to resultset
        - Refactor of the exception handling system (now everything is a
          DBIx::Class::Exception object)
