Finish adding interactive tests from Blodwen This involved implementing the 'TryWithImplicits' hack for allowing unbound implicits in types with case blocks

1/1: Building Door (Door.idr)
More base libraries This has shown up a problem with 'case' which is hard to fix - since it works by generating a function with the appropriate type, it's hard to ensure that let bindings computational behaviour is propagated while maintaining appropriate dependencies between arguments and keeping the let so that it only evaluates once. So, I've disabled the computational behaviour of 'let' inside case blocks. I hope this isn't a big inconvenience (there are workarounds if it's ever needed, anyway).

Auto implicit search fix Can't use a local which has 'erased' as its type, since that's just been substituted in while working out how many arguments a local function needs to have. Also need to ensure we've searched for default hints when encountering IBindImplicits rather than after because otherwise it might find the wrong instance. Both these problems result it terms which don't type check getting past the elaborator! So, also added a --debug-elab-check flag to check the result of elaboration. It's not on by default because there are cases where it really hurts performance, typically when inferring implicits with lots of sharing. So we'll keep it as a debug flag, for now at least.
