MoP patch for exp2

Updated to be compatible with MoP. I take no credit for the creation of this addon, and the credit should go to the original author Monrasi. Replaced Ace2 calls and embeds with Ace3. The slash commands do not currently work. Once I figure them out I will put out another patch to fix them.

Currently the default chat frame is set to chat frame 3. To change this, open the Exp2.lua and find the following section:

local defaults = {
	profile = {
		frame = 3
	}
}
