Exponentcms Exponent CMS → 2.4.0

We still support php v5.2.1 (in Exp v2.3.2), but if things seem to break prior to a release, it many times relates to calling methods not supported in php versions prior to v5.3 which do not support referencing the class using a variable, or late static bindings...therefore requiring us to use method_exists() & call_user_func() which makes the code much less readable.
