Add fantasy-land integration for valid pointfree functions

[evilsoft]

Now that we have the types working with fantasy-land functions from other libs, makes sense to make the integration both ways. All of the pointfree functions that have corresponding fantasy-land definitions should check for the namespace. These functions should check if the fantasy-land methods exist first and then fall back to the "public" if it does not exist.

Got the last bit for this done (except for traverse and ap).
closing.
