Check wxPrintf etc. arguments types.

Implements checks similar to gcc's compile-time checks: verify that the
arguments are of correct types. This works partially at compile time
(e.g. passing an object as argument fails to compile) and partially at
runtime (assert if the specifier doesn't match the type).
