Guhs

A fix for the FTB Quests chapters. Same requirements as 1.1.2.

FTB Quests: nothing is locked any more

• No quest waits for "Guh!" any more. Before, every quest hung (through a chain of lines) behind the very first quest. FTB Quests did remember what you had already done, but didn't tick it off: if you claimed "Guh!" late, a whole Guhdex of seen guhs could stay at 0 completed. Now every quest ticks itself off as soon as you've done it, in any order, also when you did it before (seen guhs, tamed guhs, advancements). Only the stomach sizes in De Guhmaag still come after each other.
• Existing worlds are repaired. Quests that were stuck at "done, but not ticked off" are ticked off by themselves a few seconds after you join (and then every 2 minutes).
• The lines between quests are gone; the section headers still say what comes logically first ("Komt na: ...").
