Make the "Reset Settings" button in Epic Menu reset springsettings

[GoogleFrog]

Many settings in epicmenu_conf have the springsetting key. This causes them to read their value from springsettings, and set springsettings when they are changed. All menus have a "Reset Settings" button at the bottom, that people expect to reset their settings. However, this does not reset springsettings settings, because the settings rely on springsettings for defaults.

Not even deleting the whole LuaUI folder resets these settings for people, and deleting springsettings.cfg is the surest way to break someone's install, because Chobby won't redeploy it (since it already did so once), so the player will be left with a bunch of broken Spring defaults.
