Comment(by markk):

 (In [25025]) Fix destruction of the OSD class.

 Firstly, ensure the OSD object is deleted before VideoOutput as
 MythImages in the OSD/UI cache are 'owned' by the painter object within
 VideoOutput.

 Secondly, delete the OSD screens immmediately - which avoids sundry
 potential issues with referencing already deleted objects.

 Should fix the subtitling and MHEG crashes/hangs seen since the osd
 branch merge.

 Refs #7650.
