Enhancement/Feature Request: zap fixed amount via emoji

[merciero]

Problem we want to solve:

• Make it easier for people to send sats
• writing command lines is not intuitive and basically would kill the use case in most cases as too complex or time consuming or easy to forget the syntax
• Implement the ability to send sats related to one specific comment and not just a person in general (zap concept from Nostr)

It turns out we should be able to implement the same approach https://www.zapplepay.com/ did:

• Detect when a user is using a specific emoji reaction, for example ⚡
• When the bot detects ⚡ , it would send sats to the owner of the post the the reaction ⚡ belongs to.
• If either one of the 2 people do not have lightning tip setup, a message DM is sent to them
• Users would also get notified when they got zap: from whom, reminder of the amount and which comment it is related to

Other things to consider (probably not so much for MVP though:

• Should the group admin have the ability to pick which emoji is used, or should we let each user pick?
• if users can pick, how?
• Users may customize the fixed amount to give
• How would other people know that the zap went through (that both people had lightning tip setup), should the bot post a message on the same group instead of DM?
