got rid of the aux-function on the raw level, by defining it with function on the quotient level

Lets finally abstract lists.

Core Haskell can now use proper strings.

Automatically compute support if only one type of Abs is present in the type.

Manually proved TySch support; All properties of TySch now true.

Generalize Abs_eq_iff.

Minor fix.

New compose lemmas. Reverted alpha_gen sym/trans changes. Equivp for alpha_res should work now.
