Setting to disable gambling, minor patch notes

For users who don't want to be subject to any games of chance, be it because of a proven inability to control yourself with gambling—not naming any names—or for any other reason, there is now a 'Can Gamble' setting in:

When disabled, you cannot use the blackjack or slots commands, access the lottery, or receive treasure chests. If you already started a game of blackjack or have outstanding lottery tickets, these will pay out as expected.

The setting has been enabled by default. For users who like losing all of their money every time they get enough DC to clear the minimum bet size, nothing has changed and no action is required.

Minor Patch Notes

• The navigation bar is now much less cluttered and has been rearranged to prioritize the most useful links. Lesser-used icons have been moved to the sidebar, or the hamburger menu on mobile. The sidebar navigation icons now also include the Marseys list, badges list, and modlog—I don't think we actually had links to the first two anywhere, and the third was hard to find.

• The delayed vote color animation in the recent UI changes has been removed.

• The lottery modal popup should behave better on mobile. (h/t @nekobit)

• Poll voters on ghosted threads are now ghosted too. Private votes! (h/t @Aevann)

• RSS feeds have more valid syntax and should™ work with more clients now. (thanks to our friends at WPD for providing a patch)

• Jannies: meme jannies are no longer a thing, and handing out mops via the UI has been removed. We had too many, and after Joan's recent purge, it was decided that forcing the local codecels to open a database prompt to add new ones would cut down on jannie quantity.
