QMovie: Add lastError and lastErrorString getters

Browse Source 
QMovie has an error signal, but it is not possible for users to
"catch" all errors, for instance, if they occur at construction time, and
furthermore, it may not be convenient to add interception of the signal
just to find out what the error was.

[ChangeLog][QtGui][QMovie] Added lastError and lastErrorString accessors,
as a convenience over connecting to the error() signal.
