command.c: Split property OSD display from property commands
The function set_property_command() handles commands that require only changing a property and then possibly displaying the new value on the OSD somehow. Split it into two parts: one that executes commands by doing property manipulation according to a table, and one that displays the value of a given property on the OSD in a manner listed for that property in another table. The goal is to allow using the OSD-display code and information in generic commands that take the property name as an argument. Splitting the table in two was not strictly necessary - I could have kept it as a single table with possibly dummy field values for entries that only make sense for one part of the split function or the other. However I think splitting it is cleaner and more readable.
