* Replaced $('body').trigger('aposReady') with apos.emit('ready')
* For bc, apos.emit('ready') also triggers aposReady on the body; the same rule applies to all apos.emit events. This bc feature will go away in 0.6
* Added apos.on('ready') handlers to invoke enableSingletons and enablePlayers, no need to invoke them separately
* apos.enableAreas is now a do-nothing function for bc; going away in 0.6
* apos.sslIfNeeded turns an http: URL into an https: URL if the current page is https
