EmojiOne v2.2.7 Installer

This is probably the last release ever of this flashable ZIP because EmojiOne chose to close up their emoji set: https://www.emojione.com/blog/emojione-30-new-licensing-explained

This ZIP:

• Uses last free and open EmojiOne font, the 2.2.7 version.
• Backups previous installed font to /system/fonts/NotoColorEmoji.ttf.old
• Survives OTA upgrades with an addon.d script
