Title: AR supporting new int4range and int8range data type on PostgreSQL >= 9.2

Hello all!

The PostgreSQL version 9.2 and higher supports a [Range Types](http://www.postgresql.org/docs/9.2/static/rangetypes.html). I think that would be nice if AR supports its too. For now I just finished intrange type.

Thanks.
