v1.1.0

• Improved performance (and fixed some timing bugs) by replacing custom internal batching logic with Angular's $evalAsync().
• The $$added(), $$updated(), $$moved(), and $$removed() methods on $firebaseArray can now optionally return a promise (thanks to @jamestalmage).
• The new keyword is now optional for services which use $extend() to add functionality to $firebaseArray and $firebaseObject.
• Removed unnecessary debug logging in $firebaseArray.$destroy().
• $waitForAuth() and $requireAuth() now properly detect authentication state changes.
• Fixed cases where $$error() was being called on null objects.
• Resolved inconsistent argument validation in $changeEmail() (thanks to @whitneyit).
