Feature request: cycle through modes

[sheinz]

First of all thanks for such a nice tool!

I would like to hook this tool to the "display" key on my laptop. So, just by hitting a single key I can cycle through different display modes. (I'm using i3 wm)

I can try to implement such feature myself but there's one question. Whether to store current mode or try to guess it from the xrand output.

Thanks @sheinz for the feedback.

I will add soon a new option called -n [EXTEND] as "next" to cycle through different 2-monitors display modes which are:

1. Preferred monitor only
2. Second monitor only
3. Duplication
4. Extend (whose the side is given with EXTEND)
5. Mirror

PS: back from holidays.
