Ree/games fixes

A few more tweaks to the Games page:

• If the menubar has been enabled in the settings, then show it, and hide the Connect button instead.
• If the user has already selected a screen size >= 35 rows, then don't resize to 80x35 for minesweeper
• Shrink the font if the new 35 row client is too tall for the browser window
