we restored the scripts of \lambda\delta version 1

last commit for helena 0.8.2
- a check was missing in the comparator
- new textual syntax for \lambda\delta "Version 4"
(exp_math files updated accordingly)

level disambiguation cmpleted! the Grafite file is succesfully generated.
Matite cannot compiled it yet since it seems to freeze on notion 2760.
We divided the Grafite file in 7 parts for convenience.

typechecking is approx. fast as before,
validation is slightly faster than typechecking.
for now the new RTM is slightly slower than the old one

0 (original)
1 (no eta-conversion)
2 (no eta-conversion, no @-typing)
