improving code quality thanks to Florian's code review

renaming code_pred_intros to code_pred_intro * * * adopted alternative definitions for the predicate compiler to new attribute name

announcing the predicate compiler in NEWS and CONTRIBUTORS

new names for predicate functions in the predicate compiler * * * adopting examples of the predicate compiler

removed deprecated mode annotation parser; renamed accepted mode annotation parser to nicer naming

added another example to the predicate compiler * * * tuning examples

changed modes to expected_modes; added UNION to code_pred_inlining; fixed some examples; tuned

removed dummy setup for predicate compiler commands as the compiler is now part of HOL-Main

adopted predicate compiler examples to new syntax for modes

added interface of user proposals for names of generated constants

first steps towards a new mode datastructure; new syntax for mode annotations and new output of modes

adding more tests for the values command; adding some forbidden constants to inductify * * * added further testcase for values command

Enables tests for locale functionality that is now available.
