2010-04-28 wenzelm 2010-04-28 more systematic naming of tsig operations;

2010-03-06 wenzelm 2010-03-06 provide ProofContext.def_type depending on "pattern" mode;
2010-03-03 wenzelm 2010-03-03 authentic syntax for classes and type constructors; read/intern formal entities just after raw parsing, extern just before final pretty printing; discontinued _class token translation; moved Local_Syntax.extern_term to Syntax/printer.ML; misc tuning;
2010-03-01 wenzelm 2010-03-01 more uniform treatment of syntax for types vs. consts;
2010-02-27 wenzelm 2010-02-27 clarified ProofContext.read_const(_proper)/Args.const(_proper) wrt. strict logical consts;
