Added experimental Viber support.

And also (because why not) an experimental way to add any intent support.

Will it be useful? No idea!

I also made visual changes in the settings screen, it was too long, now they are grouped into one of three groups.

Edit: An issue was discovered regarding the keep prefix feature. A fix was sent for review, with the same version.
