Wakaru 3.1.0

• New and Improved Themes! (This is the only thing you would want this for.)
  • There are now up to seven default themes. The new additions are 'Yotsuba' and 'Yotsuba B', so your board can look like any other board, and 'Dark Green' since 'Tomorrow' is bland.
• A few configuration settings have been changed, such as 'index.html' being the new 'wakaba.html', number of replies shown on the board being decreased, and max bumps being increased.
• Some small changes to the board's look. The CSS for code tags and spoiler tags are no longer stored away in individual CSS files. Also, added in a patch for returning to a thread/board.
• The rules.html file only has one bullet point instead of three, as inspired by Futaba Channel.
• Your image board can now have the dreaded 'Month/Day/Year' date format!
• Posters can use spoiler tags by surrounding text with %%, as inspired by the Russian IIchan.
• Updated spam definitions to the latest version.
