Configurable layout cycle order

[thiswillbeyourgithub]

Hi,

I don't think this can be done currently but I think it would be great if the config could accept a list of string that represents the order of the layout. This way we could also not include a layout we never use, which is handy as right now I didn't find a way to disable a layout entirely or from scroll.

For example I could have a special shortcut to toggle a specific layout, and not want this layout to be suggested when I'm cycling the layout.

The config.toml file now has this additional entry, which can be used to define the used cycling layouts and there appropriate order:

# List of tiling layouts used for next/previous layout cycle ([] = default).
tiling_cycle = [
    "vertical-left",
    "vertical-right",
    "horizontal-top",
    "horizontal-bottom",
]
