Improve the casing macros

Make GTM_STATIC_CAST(className, object) and GTM_DYNAMIC_CAST(className, object)
return objects that are type-casted to className *, instead of id. This enables
access to properties on the casted objects, e.g.

  GTM_STATIC_CAST(NSString, object).length

which wouldn't work previously, since accessing .length on an id type
(correctly) results in a compiler error.
