Allow specification of the horizontal/vertical layout

[shalpin]

At present rat makes the decision for whether splits are horizontal or vertical. Could this be changed so that the user can decide, possibly via the .ratrc?

What do folks think about having a keybinding to toggle between horizontal/vertical? So the default would be the current "responsive" behavior (dependent on terminal width), but a keybinding would toggle between forced horizontal and forced vertical.

I would like that. It would be nice though if I could use an option to the rat command or in the rc so that I could set my default preference when I start rat. The way I had envisaged it working was that I could pass an option to a new mode to specify horizontal or vertical for each subsequent split.

I'm imagining a new top-level keyword option (sibling to mode, bindkey, source) that could be used to configure global options. Maybe something like this?

option <option-name> <option-value>

e.g.

option split-direction horizontal

Could then define an action in action.go to be used like so:

bindkey | toggle-split-direction
