Basic TTC saving and loading now works
...
Only save the parts of terms and definitions which are needed for
typechecking and evaluation (so, for example, we don't need types for
machine generated metavariables, don't need types on lambdas, etc).

Er, that is to say, evaluation of a 'main' expression
'plus (S (S Z)) (S (S Z))' is now printing the right answer.

...
This means we have unbound implicits in types now

Implement inferLambda
...
This checks lambdas where the type isn't immediately a pi binder. First
normalises, if that doesn't work, just guesses and unifies with the
expected type.
