support for jEdit Navigator plugin;

more permissive Session.update_options: this is wired to jEdit PropertiesChanged, which may occur before the prover is started;

added option to Mirabelle

divide_minus_left divide_minus_right are in field_simps but are not default simprules

removing simprule status for divide_minus_left and divide_minus_right

merged;

tuned rendering -- take 1px line border into account;

revert ce37fcb30cf2 for the sake of Mac OS X -- let some event listeners of jEdit reset the cursor;

tuned white space;

use Z3 TPTP cores rather than proofs since the latter are somewhat broken

tuned spaces

merged

add missing adaptation for narrowing to work with variables of type integer => integer

merged

added ML antiquotation @{print};

afford larger full_index, to save a few milliseconds during rendering (notably text_overview);

improved parsing of "z3_tptp" proofs

merged

more direct warning within persistent Protocol.Status; consider Markup.ERROR (e.g. from Output.error_message without exception) as failure; tuned;

clarified Version.syntax -- avoid guessing initial situation;

more abstract Prover.Syntax, as proposed by Carst Tankink;

tuned signature (see also 0850d43cb355);

slightly more readable protocol trace (NB1: prover input is always marked as <prover_command/>; NB2: adding indentation would invalidate the XML);

recovered public command_line from d92eb5c3960d, which is important for alternative prover processes;

tuned rendering for 5 different look-and-feels;

more symbol abbrevs, e.g. relevant for list comprehension in HOL/List.thy or HOL/Library/Monad_Syntax.thy;

more general prover operations;

tuned signature -- pro forma;

more general prover operations;
