Add ability to supply an alternative sql "view" for lists views

[mattbrailsford]

I've seen a couple of people now use SQL views as a nice quick way to supporting joining data for the list views and then telling peta poco to use the view instead of the raw table.

The problem with this is that if you need editing support, then for the editor you want to go back to using the the raw table.

What would be good then is to be able to signify in the listview config to use an alternative sql view instead the default table. This was people can customise the list view without creating a full on custom repo whilst still being able to edit.

This sounds like a great idea btw @mattbrailsford, would definitely come in handy.
