json-rpc: fix resetting a datetime property through VideoLibrary.SetFooDetails
[omxplayer] When setting fullscreen flag we don't want noaspect

We set the fullscreen on 3d videos to avoid scaling breaking the 3d affect.
However we also set the noaspect flag which means widescreen videos (e.g. 1920x800) will get stretched vertically which is unwanted.
[thumbs] don't use a separate class instance in CProgramThumbLoader::FillThumb
[thumbs] don't set an empty thumb in C(Video|Music)ThumbLoader::FillThumb. Fixes #15007.
