Added proof_state and functions to control it in controller_itp.
Tried to add a test case for it inside the command p to put a big
P next to a goal that is proved.
It is currently buggy. Needs investigating and cleaning.

+ modify the command that print the sessino tree to specify where we are in the tree with "**"
+ add some more comprehensible error messages to wraper function for parsing

"parsing" of these strings is delayed in the transformations themselves,
because in case such an argument must be interpreted as a term, the
task itself is needed do perform name resolution.

Incidentally, saving transformations with arguments in sessions is not an
issue anymore

Adapted work on nearest_goal_right to be able to use it why3shell.
Now should be able to apply transformation and proof on current goal. Also
able to print the current tree and goal. Requires testing.

It finished for why3prove but not finishedfor why3ide yet.

If these are set, the prover is asked for counter-example and if the counter-example is got, it is displayed.

characters '. ", <, > and &

(no yet displayed in IDE)

new goals are associated to old goals directly in the order they appear.
they are all marked obsolete, unless the theory itself is found non
obsolete (thanks to the new checksums for theories)

in other words, reloading a session on a file that did not change results
in non-obsolete goals, even if checksums and shapes are absent (e.g. if
the file was not put under version control)

and merge the why3 and why3session libraries back into one.
