correlate AS fieldname

[mrenvoize]

As discussed on IRC 16.52 June 9th 2016, it would be nice to allow for 'nameing a correlate field at the database level' to allow for sorting on the correlate result.

We discussed adding the following to the correlate call syntax:

 $rs->correlate('foo', { as => 'foo' });

Seems the above syntax 'aint possible'.. so there was talk about creating a new piece to ::Helper:ResultSet::Util

 $rs->as($as_query, 'newalias');
