[Maypole] 2.07 PR

[Simon Flack]

I'm planning to release Mayole 2.07 this week. It'll fix some of the 
outstanding issues that have been raised in the last month.

For now, a preview is available at:
	http://simonflack.com/scratch/Maypole-2.07.tar.gz

I'd appreciate some feedback on this this release before I upload it to 
the CPAN.

Here's the relevant block from the Changes file:

Internal changes:
- Removed Maypole::Model->description.

Fixes:
- Model->process() shouldn't set $r->objects() to a list with a single, 
undefined element
- Fixed overriding $r->template_args->{classmetadata} in M::V::Base 
(Thanks to Dave Howorth for spotting the mistake)
- #9473: Maypole::Model::CDBI->related_class (Thanks David Baird)
- #9434: M::M::CDBI->search generated "uninitialized value" warnings

Templates:
- The addnew template will attempt to prefill form fields with
request parameters
- edit template includes 'addnew' if there is no object to edit

Thanks

Simon
