Hotfix v0.7.7: looting bag, Esc closes windows and many fixes

A bug-fix round for Update v0.7.7. No new content, just things that were broken.

Fixes

• Looting bag: Open and Close work again, Settings sets what happens when you use an item on the bag, and you can use items on it, check it and fill it in combat. Taking items out still goes through the bank.
• Esc now closes the current interface by default (you can switch it off in Settings). Windows where closing could cost you items, like raid chests and the first-login mode setup, ignore it.
• Level-up box: it closes with Esc, a click on the ground or a walk click, and the level-up pop-up setting works again.
• Keybinds are saved with your character, and a client crash when a group ironman spoke in chat is fixed.
• Sailing: build-spot plates face the right way, and the sloop sailor steers beside the tiller.
• Fixed the Revenant Caves entrance, the blank autocast list, a long Sailing route search, and many player reports: milking cows, feather packs, Rune Mysteries, cooking and more.
