Now that custom forms can be used by multiple object types, we need the
ability to specify if a field should be shown/hidden on certain
objects.For example, a custom form that is used for Requests and
Projects may have certain fields that are not required when submitting
the request, but need to be required to populate when converting the
request to a project. Currently the only solution is to copy the form
and go back to having separate forms for different object types.
