Option to construct "///" links

[sprig]

Now that there are options, it would be nice to add support for "///" links for people with xdg-open problems, e.g. #29, #27, #16)

I have the same problem on my Windows machine with Firefox. Right now, I can't use this extension precisely for this reason. (I added /// to the code myself, but then Firefox won't accept the plugin because it's not signed.)

Hi,

Yes, this option seems a good idea...I just update my system to Ubuntu 17.10 and capture stop working without adding a third slash.

Best regards.

gio open seems to not handle org-protocol:// urls correctly. Adding a third / gets things working! If you do not wish to add an option, I think it could be made the default, without breaking others.
