Replacing "cast surgery" in LetIn by a proper field (see PR #404).
This is a patch fulfilling the relevant remark of Maxime that an
explicit information at the ML type level would be better than "cast
surgery" to carry the optional type of a let-in.
There are a very few semantic changes.
- a "(x:t:=c)" in a block of binders is now written in the more
standard way "(x:=c:t)"
- in notations, the type of a let-in is not displayed if not
explicitly asked so.
See discussion at PR #417 for more information.
