Prompt for and accept battle between two users

[dlrocker]

Need a way to for a primary user to initiate a battle with a secondary party/discord user. It should be something like the following:

• Primary user initiates battle

  p!ka battle @<secondary user>

• Secondary party/discord user accepts or declines

  accepts

  p!ka accept battle

  or

  p!ka decline battle

For this item it should not start a battle. Instead, it should simply print a response of either:

Starting battle between <primary user> and <secondary user>

in the case of accept or

<primary user>'s request to battle <secondary user> was declined! <secondary user> is scared!

in the case of decline
