Title: Removing progress computation logic from plugin wrapper

I think that wrapper-approach must minimize result transformations between end-users and cordova plugins.
Users can't currently use 'loaded' or 'total' properties of progressEvent because of percentage computation.
I think its better not to transform plugin result, users can check cordova doc for FileTransfert plugin, see progressEvent structure, and decide what to do.
