do not apply string_of_term to dummy-typed syntactic constants (ensures that uncheck phases work on well-typed terms)

modify background theory where it is actually required (cf. 51dfdcd88e84);
2013-07-18, by wenzelm

explicit padding on command boundary for "auto" generated sendback -- do not replace the corresponding goal command, but append to it;
2013-07-18, by wenzelm
immutable theory values with full stamp record of every update (increase of stamp size for HOL: 20000 -> 100000, JinjaThreads: 65000 -> 300000) -- minimal measurable impact on inference kernel performance;

more opportunistic string_of_clause, to make double-sure its Syntax.string_of_term uncheck phase does not crash, and thus bomb ambiguous input via failed composition of warning (e.g. HOL/Imperative_HOL/ex/Linked_List.thy: lemma merge_simps);

non-strict "Quiet" mode, to avoid odd crash of code_pred/after_qed due to ill-typed use of string_of_clause (e.g. in JinjaThreads/Common/Decl.thy of AFP/d1bb08f92ce5);
2013-07-17, by wenzelm
take context from static theory, not dynamic theory certificate;

deactivate/revoke mouse event more thoroughly, to avoid "Implicit change of text area buffer";
2013-07-15, by wenzelm
retain compile-time context visibility, which is particularly important for "apply tactic";
