A hacky way of hardcoding controller arguments. Because page arguments are
translated onto the attributes variable and the attributes are used for
arguements via reflection, this lets you push arguments onto the controller
that aren't on the path. This is hacky but so was the original version and
it shouldn't cause a problem as long as path arguments don't share a name
which would have caused problems anyways.
