Ability to gift coins to another user

[ryanchartrand]

New command: /gift-coins [@user] [amount]

Functionality: gives coins to another user, subtracts from the user doing the command.

If the user does not have the amount of coins they are trying to give, send an error message: "Sorry, you don't have that many coins yet. Try again with a lesser amount."

If the user identified in the command does not exist, send an error message: "Sorry, that user doesn't exist. Please try again."

If the user does have the amount of coins:

• subtract the coins from the user doing the command and award the amount of coins to the user they identified.
• Send a success message to the gifter: "Gift successfully sent! Good on ya, mate. :fives:"
• Send a success message to the giftee: "Well, it's your lucky day. You just received [amount] :coin: from [gifter @username]. There's no greater gift than a 'thank you' in return :wink:"

@ryanchartrand how many coins a does a user have? At Xfive, each of us has 3 coins per month. If we don't distribute all of them during a month, they're gone and starting from 1st day of the new month, we have again 3 coins to distribute.

@malgorzatajezierska They earn them individually through community activities, so they aren't given them until they earn them. They currently don't ever expire, although that could become an option one day if we find people aren't spending them (most do spend them which is good).
