Update 1.6.0b29s4

Changelog:

• Added Reaction-Roles System </manage reactionroles:1322247084325339178>

• Fixed /backup create and /backup restore (There was a problem with the uuid generrien. The restore system is not quite perfect yet.)

• Fixed Youtube 404 Error when Channel not found

• Added /reactionroles to the DisBotAPI

• Added Reactionrole placeholder {allroles}, {member.tag}, {member.id}, {member.username} (Tell me if you need more)

• Fixed some smal problem...

I hope you are not angry that it is so little. I am now coding something on the website. And then on the Welcome/Leave/Backup/Giveaway.
