2011-08-25 blanchet handle nonmangled monomorphich the same way as mangled monomorphic when it comes to helper -- otherwise we can end up generating too tight type guards
2011-08-25 blanchet avoid using ":" for anything but systematic type tag annotations, because Hurd's Metis gives it that special semantics

2011-08-25 krauss lemma Compl_insert: "- insert x A = (-A) - {x}"
2011-08-25 boehmes avoid variable clashes by properly incrementing indices
2011-08-25 boehmes improved completeness and efficiency of Z3 proof reconstruction, especially by an improved handling of Skolemization
2011-08-24 blanchet include chained facts for minimizer, otherwise it won't work
2011-08-24 blanchet remove Vampire imconplete proof detection -- the bug it was trying to work around has been fixed in version 1.8, and the check is too sensitive anyway
