localized properties_for_sort

@tailrec annotation;

renamed "rev" to "reverse" following usual Scala conventions;

parse_spans: cover full range including adjacent well-formed commands -- intermediate ignored and malformed commands are reparsed as well;

added rev_iterator;

tuned;

access statically typed dockable windows;

simplified dockables using class Dockable;

generic dockable window;

separate event bus and dockable for raw output (stdout);

more Mac OS problems;

ignore system messages;

use proper ISABELLE_PLATFORM instead of adhoc uname;

refrain from using bold within the term language -- looks odd in Lobo with error/warning background;

tuned;

removed timing;

rendering information and style sheets via settings; generalized Isabelle_System.try_read; prefer getenv_strict in most situations;

more brackets -- unaligned to prevent odd auto-indentation;

merged

adjusted to changes in Mapping.thy

merged

tuned

more lemmas about mappings, in particular keys

refined

nats in Haskell are readable

Let rsp and prs in fun_rel/fun_map format

tuned zoom_box; tuned tooltips;

print calculation result in the context where the fact is actually defined -- proper externing; misc tuning;

future_job: propagate current Position.thread_data to the forked job -- this is important to provide a default position, e.g. for parallelizied Goal.prove within a package (proper command transactions are wrapped via Toplevel.setmp_thread_position);

some message styling;
