A re-implementation of the classic Mozilla/Netscape theme

• fixed tabs on OS X
• added all classic ChatZilla user status icons/graphics
• added all classic ChatZilla smileys/emoticons. Some created by me to fill in the gaps.
• added all classic smileys to communicator (primarily for mailnews stuff)
• added classic all icons to messenger/accountcentral
• added classic notification icon for new mail
• added retro icons from broken/outdated “Classic Default 0.8” extension to add-on manager. Works with OAM as well
• clean about:addons .css imported from the GNU/Linux version (OS X defaults are particularly ugly)
• added retro error, exclaim, message, question, etc. graphics in global/icons
• added light autoscroll as default. dark autoscroll also included (defaults to dark on OS X, looks bad, changed to light).
• added support for web notifications in modern versions of seamonkey
• added retro icons for context menus/urlbar picon (warning, error, info, question)
• Fixed mailnews reply icons for reply/forward + offline/normal/attachment emails

TODO: Some stuff is still OS X-specific (primarily navigator/{pageinfo/tabbrowser}.css)
