Subject: Properly set TextureEntry.MediaFlags when a media texture is set

Media flags is cleared via a direct TextureEntry update from the client.  If the clearing leaves no media textures on the prim, then a CAP ObjectMediaUpdate is not received.  If there are still media textures present then one is received.
This change fixes drag-and-drop on Windows (and Mac?) clients.  It may also fix problems with clearing and then subsequently setting new media textures.
