Generalized binding syntax overhaul: only two new binders: `() and `{},

guessing the binding name by default and making all generalized
variables implicit. At the same time, continue refactoring of
Record/Class/Inductive etc.., getting rid of [VernacRecord]
definitively. The AST is not completely satisfying, but leaning towards 
Record/Class as restrictions of inductive (Arnaud, anyone ?).
Now, [Class] declaration bodies are either of the form [meth : type] or 
[{ meth : type ; ... }], distinguishing singleton "definitional" classes
and inductive classes based on records. The constructor syntax is
accepted ([meth1 : type1 | meth1 : type2]) but raises an error
immediately, as support for defining a class by a general inductive type
is not there yet (this is a bugfix!).
