Links to online books seem to be gone

I checked a few pages and there are no such links to Real World Haskell or Learn You a Haskell left.
Would be quite useful to have them back :-(

i think we said back then that it was low-priority to get integrate running again. i will see what i can do

We are just missing loads of links this way.
Clearly, we need to find a better way to link and to maintain those.
For now, let's keep the links alive that we have.

It looks like we are finishing this instance of course:fp with these pointers; maybe, they are not so super-critical. Anyway now with @johanneshaertel and his interests aboard and the project behind, we just make a proper effort to get this sort of feature (links to textbooks) more generally, more reliable, more explainable, maintainable, scalable (what have you) back alive.
