V1.2 Update: All's Well

This momentous update finally fixes all the bugs I know about on Windows, apart from a few lingering and very hard-to-fix ones that are unique to specific machines. (If you have one of these, please let me know.)

Bugs fixed are as follows:

- Fixed dependency issues preventing progress in the Abbas Salem quest.
- Fixed some issues with exploring the Shambles in the Dreams of the Dancing God storyline. This wasn't bugged content, it was just very punishingly difficult and quite badly designed to begin with. I think I must have been very sleep-deprived when I came up with this. Made some simple changes that improve the quest progression tenfold.
- Added a way to sell Sleepless Wretches from your cargo.
- Fixed a minor dependency issue in the procedural Journalism quests.
- Fixed a broken dialogue option in the Morbazar storyline.
- Fixed blank-screen dialogue bug in the Nicholas storyline.
- One of the dialogue options in the Library storyline didn't correctly reward guineas.
- A bug I'd already thought was fixed: Travelling via fetch-mirror to Chimer and failing the skill challenge would sometimes drop you a bit too far north. Turns out this could still happen in very rare cases. Now fixed!
