Issue: Creates double entries

[SporyTike]

It's a known problem that the site has problems to save game titles like Legend of Zelda, The - Link's Awakening. For some reasons the site changes the name to Legend of Zelda, The - Link''s Awakening after saving. But it's still possible to rename games correctly so they are shown correct on the site while using the HTML code ' instead of '. The problem is that you can't add any hashes to games with this symbol in the name because if you do it the toolkits create a new entry with the name of the selected game before the symbol. So in this case every time you try to add a hash to the game a Legend of Zelda, The - Link entry will be created.

Quotes being converted to double quotes is a server issue: https://github.com/RetroAchievements/RAWeb/blob/1881a9be7aaa2df503f35282fd8e0c3364998b80/lib/database/game.php#L1101

Not properly escaping data sent to the server should be fixed in the 0.75 toolkit, but non-ASCII characters are still not supported (see #230)
