It appears that our attributes_with_hobo_type_conversion= monkey patch
is no longer being called on create.
I could fix that, but it seems like a better idea just to get rid of
the monkey patch completely.
To do so, I'll switch from using the `select_datetime` helper to the
`datetime_select` helper. This may cause problems for some people,
because the parameter name will change from something like
foo[bar][year] to something like foo[bar(1i)]
This would be a breaking change very late in our development cycle,
but I think it's best to do it now before we hit the 2.0 mark.
thoughts?
