* Give focus to first/selected item of dropdown menus

Use short instead of numeric month, display year when different year

KeyboardEvent.key may be physical key name (Escape, Tab, etc.)
even in text composition and it causes hotkeys or suggestion selection.
So we need to check e.which or e.isComposing.

Checking e.which also allows us to avoid Esc key on compositionend in Safari.

* Fix the hot key (j, k) does not function correctly when there is a pinned toot in account timeline.

* Fix typo

* Add custom attribute prefix

* Fix boosting own private toots.

* Run yarn manage:translations and update Japanese translations.

This fixes following cases which causes hotkey action accidentally:

* hitting Esc key to cancel text composition (mostly in CJK)

  Although events on cancelling composition are still heavily
  browser / input method dependent, but this implementation would
  covers current UI Events spec and some exceptions.

* hitting Esc key to close autocomplete suggestions

This PR changes to use keydown event instead of keyup event as well as other hotkeys.

* Fix: Switching between composing direct message and mention from menus

Previously clicking "direct message" followed by "mention" resulted in the composed status staying as "direct", along with weird spacing of items in the text area. This attempts to fix that.

* Fix: Add missing proptype check for onMention in Status component

* Add the ability to send a direct message to a user from the menu on Statuses

* Add space between "Embed" and "Mention" on expanded statuses menu

`navigator.share()` rejects Promise if user cancelled sharing, and it may
print it as an error on JavaScript console.

This patch ignores it and prints other errors on the console.
