Replace Facebook 'Angry' with 'Dislike'

Makes it feel more like a dislike button!

v1.2.1 22. 11. 2016 Minor and lazy fix where sometimes the dislike would turn into the unused confused reaction.
v1.2 22. 11. 2016 Massive code rewrite (based from my Halloween Reactions code), text now changes and the image shows on the current facebook.
v1.1 24. 02. 2016 Replaced an extra graphic I forgot.
v1.0 24. 02. 2016
