Weakaura -> WeakAura2

It seems the author of Weakaura has started a new project called Weakaura2.

v2 uses the same file structure as v1, so you can just download and install over the original and everything will work as it did before.

However, if you use curseclient, you need to uninstall the original first. Just be very careful to untick remove settings when you remove it, or you will lose all your current auras.
