I have modified the grammar for idts (sequences of identifiers with optional
type annotations). idts are generally used as in abstractions, be it
lambda-abstraction or quantifiers. It now has roughly the form
idts = pttrn*
pttrn = idt
where pttrn is a new nonterminal (type) not used anywhere else.
This means that the Pure syntax for idts is in fact unchanged.
The point is that the new nontermianl pttrn allows later extensions of this
syntax. (See, for example, HOL/Prod.thy).
The name idts is not quite accurate any longer and may become downright
confusing once pttrn has been extended. Something should be done about this,
in particular wrt to the manual.

Simplified proofs thanks to addss.

Fixed old bug in the simplifier. Term to be simplified now carries around its
maxidx. Needed for renaming rewrite or congruence rules. maxidx should be ~1
in most cases (ie no Vars), hence reasonable overhead.
