Ability to change gaps on the fly

[frostyfalls]

Missing behavior

There currently is no ability to change the {inner,outer,} gaps on the fly while running wideriver.

Desired solution

The solution I'm looking for is just to change it via an integer. Either setting it (e.g. 2) or changing it in relation to the current gaps (e.g. +4). I'd also like to be able to toggle gaps all together with the last used one, if possible (if not, I can just set it to 0).

Ideas

riverctl send-layout-cmd wideriver "--{inner-,outer-,}gaps {2,4+,toggle}"

That sounds very useful, we can implement it.

A toggle is possible for all three and desirable so that the user does not have to know current state:

  --(no-)smart-gaps
  --inner-gaps
  --outer-gaps

While we are in there, width and colour can receive the same treatment, with toggles for widths.
