Clean page titles and a game-styled scene picker on the map before the next release

Before the next release, every page of miside.wiki must pass our own style rules. The live site still shows long dashes in page titles on every page, such as the home page and Mita pages, and the map uses a plain browser dropdown for choosing a scene.

Page titles are being rewritten in each language to read cleanly, and the map's scene picker is being replaced by the game-styled selector that keeps right to left layout, keyboard use and map history working.

Game text itself is never edited to pass these rules. Each changed page will be checked in the browser on a full test version of the site before release.
