Use GtkOverlay to show the loading message

Remove the EvLoadingWindow from libview and move the implementation to
the shell using a EvLoadingMessage widget and GtkOverlay. EvView has now
a is-loading property that allows the users to implement their own
loading notification system. This fixes several realted to the loading
window.
