Only format smarty aliases as money if specified

Only format smarty aliases as money if specified

smarty aliases allow tokens to be assigned to the template as smarty variables. They are very new,
have only been implemented in these 2 places and are not accessible from outside of core, which
both have unit test cover.

When trying to extend it to cover another variable (totalTaxAmount) in another template I found
that a raw format is appropriate. I think it makes sense to explicitly specify.
