Enable Emojis on Windows and Linux

This patch enables emojis for Linux and Windows. In windows, currently the emojis are only black and white, due to some inconsistencies in the UI. For Linux the Noto Colour Emoji font (https://www.google.com/get/noto/) is used. The client must be build with Qt 5.6 or newer to support the emoji characters. Test-Information: Tested the changes with Qt 5.8 on Windows 10 and Linux Ubuntu 17.10. Built and tested the appimage on Ubuntu 17.10 and Ubuntu 16.04.
