Itt_int_ext: more conversions added to reduce resource

Itt_int_arih: first working version of arithT!!!
You can observe proof of test rule and try to replace it with just arithT
in the root.
While now arithT knows only numbers, variables and +

I've removed old Itt_int* theories and switched all the ITT to Yegor's
new theories.

1. I added new primitive rules:
     Itt_struct.exchange
     Itt_pointwise.hypSubstPointwise
     Itt_pointwise.contextSubstPointwise

   The last two rules show the differences between pointwise and pairwise functionality.
   They are valid in pointwise functionality (as well as quoationtElimination2).

2. Itt_struct3 contains some rules that derived from these new ones.
   But thesd rules are valid in both functionalities.

3. I moved definition of natural numbers to a new theory Itt_nat.
   To prove induction for natural numbers one needs Itt_struct3.
   I almost proved it (leaving some simple arithmetic subgoals, that should
   be killed by arith)

4. I defined record type.
   Itt_record is a main theory of records.
   Itt_record_exm contains some examples.

5. I add a new conversion
        * applyAllC : conv list -> conv
   that applies all conversions to all subterms and a tactic
        * rwa : conv list -> int -> tactic
        = rw (applyAllC convs)

  Principle) is added.

- Some definitions and simple facts are added to itt_int_ext

Finally, I am able to commit what I was getting to
in all these commits over the last several days.

I changed the parser to index declared opnames by its "shape" -
last string of opname + parameter types + subterm arities
instead of just the last string (as it used to be). This means that
the parser now checks whether the usage of an opname corresponds
to its declaration. This allowed me to detect numerous typos in
display forms and even some rules and rewrites and, hopefully,
will prevent people from making such typos in the future.

This is only the first pass of the implementation. I still need to:
- make sure none of my fixes broke any display forms that used to work
  because of typos cancelling each other
- update the documentation
- implement checking of shapes on the opnames specified using the
  Module!name notation (currently no checking is done on such opnames)

1.Some minor changes in old files
2.First ugly approach to Arith implementation. It just can find contradiction
  and construct contradictory inequality. Next step will be polynoms and
  inequalities normalization. It will increase range of input inequalities and
  let easily prove resulting contradictory inequality.

- Fixed a nasty bug in indEquality. Yegor, can you dbl-check, please?
- Renamed "uni_minus" to "minus".
- << (- 'a) >> is now parsed correctly as minus{'a} instead of sub{'a}.
- Rewrote Yegor's theories to use the parser shortcut for "minus".
- Fixed the minus_df.

Moved from old style conditional rewrites to rules with '~' operator instead of '<-->'.
Just now all reduce resources are commented out.

itt_int_bool_new was split into itt_int_base (beq_int, lt_bool, lt, add, uni_minus, sub, int, ind, number)
and itt_int_ext (ge_bool, le_bool, gt_bool, ge, le, gt, mul, div, rem)
