Updates the download URL

Umbaska 3 has now been released!

All information is on the download link.

Since the change log would be so long, I can't be bothered adding everything. But I've listed the major points below;

• Support for 1.8 and 1.8.7. If you use any 1.7 version, no proper support will be provided, whatsoever. //Just let 1.7 die please. <3//​
• Lots of replacements for stuff that broke. For example, Particles, Trailing, etc.​
• File management (create, read, write, delete & copy)​
• Everything from GattSk, SkSpigotAdditions, and SkExtras that may have not been added before.​
• Entity stuff​
• Noteblock stuff that doesn't work properly​
• Scoreboards​
• Armour stands​
• Worlds ​
• YAML/YML​
• Books​
• Some JSON thing​
• Amazing file management stuff (read & write with lines)​
• Clips PlaceholderAPI support​
• Debug Info option in config. If enabled, will log when effects, expressions etc. is registered. Use this if something isn't enabled properly.​
