Add HTTP::Throwable and a redirect method to Jet::Response. Jet rethrows
if it detects that Plack can handle it.
Add a VERY basic uri_for method to Response.pm
Update / Validation functionality.
Override edit_updated to NOT redirect for Config types, as this is
called w/Ajax.
Add Html type incl view, edit.
Typo fix
Modify the dbic_dumper to include a filter, so now every db column can
be changed. This is necessary for data_node.node_id, as dbic doesn't
really know about db views.

(Also there was a mistaken space-to-tab conversion)
Discard changes to keep pg and dbic happy together forever.
