Improved/quicker/easier handling of control port ranges.

 * Add "Set minimum to current value", "Set maximum to current value",
   and "Reset range" to control port context menu.

 * Only serialise properties (e.g. lv2:minimum) if they differ from
   the meta object's (prototype's, e.g. plugin) value.
