Fix mastodon.social's dark mode so that the post compose form is also in dark mode

mastodon-compose-dark-mode.css

/* this probably breaks light mode
 * totally untested
 * but it does fix my problem, which is that the 
 * mastodon.social dark mode doesn't adjust the
 * post composition window to also be in dark mode
 *
 * I activate the below using the Stylus extension
 */


.autosuggest-textarea__textarea,
div.autosuggest-textarea__suggestions:nth-child(2) > div:nth-child(1),

Thank you, much better!

For mastodon.au the icons at the bottom aren't picked up (that instance uses a different software version, I guess). I added this to change them. It works, but I might not be doing it right:

/* mastodon.au */

.fa-fw,
.character-counter,
button.text-icon-button {
  color: #d8d1e8 !important;
}
