#730

I will merge #767 first for fody

add arguments of files / total commander / directory opus.
It seems that it cannot be tested with a plug-in yet, so it was tested with a command line.
I don't know how to run rx explorer as a command line.

• This item is likely to be added/changed in the future. When I tested, there was a problem that ended when the data changed slightly. It seems that there is a need for a way to be compatible with the old version of data or reset if the data does not fit. The web search plug-in has the same problem, so this kind of setting seems to require a separate solution

• I think we should make it impossible to put an argument as an empty item. If you press "done" in the blank item state, you can automatically enter and save "%d", or if the textbox length is 0, you can enter "%d" from the beginning.

• For a detailed description of the argument setting, let's add a hyperlink. I think we can fill out a document and link it.
