Original GitHub issue: https://github.com/appy-one/acebase/issues/41

Originally assigned to: @appy-one on GitHub.

Safari (on Mac & iOS) doesn't support BroadcastChannel, which is checked for in the browser IPCPeer constructor but not in its sendMessage method, which is actively used by AceBase.

This results in error "TypeError: undefined is not an object ("evaluating 'this.channel.postMessage')" and the database not being created correctly / working properly.

This affects Safari on Mac, and all browsers on iOS (they all use Safari behind the scenes)
