Allow geometry masks to work within bitmap masks

 * Declared `Audio.dataset`, which fixes Internet Explorer 10 crashing when trying to access the dataset property of the object (thanks @SirLink)
 * Previously, setting a mask on a Particle Emitter wouldn't work (it had to be set on the Emitter Manager instance), even though the mask methods and properties existed. You can now set a geometry or bitmap mask directly on an emitter.
 * The Particle Emitter Manager was missing the Mask component, even though it fully supported masking. The Mask component has now been added. You can now mask the manager, which impacts all emitters you create through it, or a specific emitter. Different emitters can have different masks, although they override the parent mask, if set.
+* You can now apply a Bitmap Mask to a Camera or Container and a Geometry Mask to a child and have it work correctly.
