UnifiedPush-AC 1.0.0

Changes

• Initial release!
  
• Updated the UnifiedPush Connector library to 3.3.2.
  
• The target version of Mozilla's Application Services can now be specified with the new as.version local Gradle property.
  
• Set certain Mozilla dependencies to compileOnly to avoid conflicts with Firefox (mozilla-central), as Fenix already builds/packages them.
