explicitly cast column types when migrating

PG doesn't support implicit casting anymore because it could incur data
loss.  This explicitly casts data types using the API in upstream Rails.

This depends on manageiq/rails#15
Bump to rails fork containing support for casting.

connection.change_column :strings, :somedate, :timestamp, cast_as: :timestamp
connection.change_column :strings, :somedate, :timestamp, using: 'CAST("somedate" AS timestamp)'
remove `virtual_columns=`

this reduces the surface area of the virtual colums api, and will make
it easier to port to Rails 4
remove `virtual_reflections=`

We are not using this method in the application, and removing it will
ease porting virtual columns and reflections to Rails 4
