Also put the selection on first subgoal when applying transformation.

Complete creation of the tree session in ide(todo: decide what to print).
Added a table proofnodeID -> gtk_tree_iter to provide to callbacks.
Added callbacks that change the IDE output.

Also, added a debug flag to be raised when matching of apply fail.
To do that, I changed exception NoMatch so that it returns the terms
that cant be matched.
This needs some testing.

Added a last set which is build at the same time of the name_tables which
is a map from id to list of decls where id is used. This has to be tested
if this is actually efficient (time and memory). If not, we can still
disallow it with a boolean.

Ident closer to the goal have lower disambiguation numbers.
We do that by first puting all declarations in a list and then iter on
it.
Also removing useless comments in test_argument and args_wrapper.

present.

* call_provers.ml
(prover_update): Adding unimplemented errors that reflects the cases of
proof_attempt_status. Otherwise, proof_attempt_status is a list of cases
that are never reached.
* controller_itp.ml
(proof_attempt_status): Added Uninstalled case in proof_attempt_status.
Launched in replay when asked to replay something not installed.
(print_trans_status): Adding a ! when proof is valid for debugging
reasons.
(report): Added a report type for replay reporting of differences.
(print_report): printing function for report.
(replay_print): callback used with replay to print the report at the end.
(replay): Function that replays all proof attempts of the session.

* session_itp.ml
(session_iter_proof_attempt): Added the proofNodeID the fold function
for convenience.
* why3shell.ml
(test_replay): Added to test replay.

Possibility to add env to transformation via args_wrapper (ugly).

Rewrite and replace.

Seemed useful because the declaration might not be displayed.

On some examples, goal was cut when first end was encountered.

- add session directory and restore old session file mechanism

I think it is currently passed into the command.
