command: make "add <property> 0" not change the value
The value 0 was treated specially, and effectively forced the increment to 1. Interestingly, passing 0 or no value also does not include the scale (from touchpads etc.), but this is probably an accidental behavior that was never intentionally added. Simplify it and make the default increment 1. 0 now means what it should: the value will not be changed. This is not particularly useful, but on the other hand there is no need for surprising and unintuitive semantics. OARG_CYCLEDIR() failed to apply the default value, because m_option_type_cycle_dir was missing a copy handler - add this too.
