GuildWiki:Wintersday/Wiki decorations

Plan: To make the Wiki look more Wintersdayish.

Current ideas

 * The GuildWiki icon: Change to Peppermint Shield with Candy Canes behind it
 * Change the favicon to a Birthday Present icon
 * Have icicles hanging off the top of the page
 * Javascript snowball rolls across main page
 * Something with snow (maybe change site background image to snow?)
 * ...(propose on talk)
