command: when changing a property, allow showing an extra OSD message

Browse Source 
This is for properties that normally show a bar, and thus do not show an
OSD message (as per classic mplayer behavior). Setting an extra_msg
allows showing an OSD message anyway, except if OSD messages are
explicitly suppressed.

This refactors the whole show_property_osd() function a bit, and
replaces the weird sep field with a more general method.
