Add [TypeChecking=Interface] to XSLTProcessor interface
Also make affected arguments (to importNode() and transformTo*()) non-
optional, like in Firefox. It makes no sense to call either function
without any of the arguments, and the previous behavior was to fail
silently in that case.
Also make the return type of transformTo*() nullable to reflect how they
are actually implemented; they currently return null on failure.
