Feature Request: add Alt + Q shortcut to hard-wrap lines at the preconfigured "ruler" column width

Description of the problem or steps to reproduce

Depends on: https://github.com/zyedidia/micro/issues/2694

In Sublime Text I can hard-wrap using Alt + Q. This will hard-wrap at the first specified ruler position in the settings. Please implement this feature in micro too.

Ex: when the first ruler is set to 80 chars, this:

I am a long line that goes beyond 80 chars. See! Look how long I am. I don't even want to be on one single line though, in truth.

...becomes this after clicking on the line and pressing Alt + Q.:

I am a long line that goes beyond 80 chars. See! Look how long I am. I don't
even want to be on one single line though, in truth.

Start by reviewing the dependency issue 2694, then inspect micro's existing ruler settings, hard-wrap behavior, and shortcut handling. Implement Alt+Q so the current line wraps at the first configured ruler column, and verify that the example long line is split at that position without changing the intended text.
