[dvdplayer] - when starting playback update the playerstate with a possi...

...ble starttime (e.x. when resuming from a bookmark).

This is one approach to fix a problem where a python addon implements the "OnPlaybackStarted" callback and queries "xbmc.Player.GetTime()" at the very first.

In the case where playback was started from a resume point (this is what the addon wants to figure out) the GetTime() might return 0 (depends on the fact that the video has no valid dts yet).

@elupus for comment - not sure if this is a sane approach for fixing the problem.
