Add new keyboard shortcut: 'M' - toggle read/unread, go to prev item

Currently there is "Toggle read/unread = m", which toggles and
then goes to the next item.

Having the opposite operation available is handy, especially when adding
new feeds and going through them from oldest to newest posts.

It seems natural to map 'M' (= shift + 'm') for this action.

Closes https://github.com/miniflux/v2/issues/1352
