Solves a bug that caused the auto statistics to refer to objects that are not
loaded in the environment, forcing them to be loaded and causing all sorts of
problems.
* Almost ready for release 0.99.1.
* Syntax changed:
*H => * as H
-H1 .. HN => -H1 .. -HN
intros => ##
pattern: in ... => {...}
* Library ported to the new syntax

Matitaweb: goto bottom can now be undone step by step and also reports errors
(basic error reporting as in advance).
Should fix a problem with the status.
Matitaweb:
1) Adds a feature to enrich automation statements with their trace (after
successful execution)
2) Introduces a different syntax (/... trace lemma1, lemma2 .../) for
system-generated traces (as opposed to user-provided)
3) Graphical update hiding system-generated traces (they are provided as
a tooltip for inspection, when hovering with the mouse pointer on the
tactic)
4) Fixes a bug in the computation of the cursor position in the script.

1. we compare the expected branching with the actual one and
prune the candidate when the latter is larger. The optimization
is meant to rule out stange applications of flexible terms,
such as the application of eq_f that always succeeds.
2. At top level, we index local equalitites for paramodulation for
each cluster (i.e. we assume metas in a same cluster shares the
same context *)

There is some gain but less than expected

-applicative_case has been rewritten and simplified;
the strategy should be clear, now.
- if we have an unkown ?n goal we instantiate it with I:True:Prop.
Due to the topological ordering of goals, ?n should not appear
in any other open goal, so its instantiation can be arbitrary.
- paramodulation is has only an implicit knowledge of the symmetry
of equality, hence it is in trouble to prove (a=b) = (b=a).
A try_sym tactic has been added to smart application to cover this
case.

New management of the resulting substitution in deep eq.
We reduced several time the goal vs the active table, possibly
resulting in a clash of names generating cyclic substitutions.

Matitaweb: added preliminary support for interactive disambiguation.
Ambiguous expressions are reported to the client and highlighted.
The possible interpretations are shown in stderr.
