[Dbix-class] Filtering module

[jackal]

Hello,

This is proposal for a filtering component, similar to 
DBIx::Class::InflateColumn
It can -modify- columns transparently. When you read column - it inflates, 
when you write - deflates.
On creating a new column, whole cycle passed - deflating for DB and inflating 
for usage.
Module can handle scalars, because of it's destination - to modify data.

Module can works together with InflateColumn:
__PACKAGE__->modify_column('passw', ...);
__PACKAGE__->inflate_column('passw', ...);

In that case, when you read - it inflates into object by InflateColumn, then 
object will be modified by ModifyColumn. When wou write - there's reverse 
process.

Kind regards, Eugeny.
