Drop non-slash commands

[NyCodeGHG]

Announcement 04.08.2021
As of today, we're going to drop support for Message Commands, the reasoning being Discord announcing deprecation for message contents for verified bots and therefore also wanting devs to move on from message commands. BankoBot will continue to allow using message commands as long as neither Discord drops our acccess to the message content or kordx.commands will migrate to being a slash commands lib. However we'll stop accepting Bug Reports for message commands and not consider compatibility with message commands for new features/commands

I think we should drop Support for non slash commands, so we can fully use the new features of discord without having to write 5k lines of Code Just for supporting both variants. When we implement this we have to find a solution for a better experience with some tag commands. Especially those which require multi line arguments.

[DRSchlaubi]

actually a good idea but we need to put it on hold as slash commands lack e.g. multi-line arguments. kordx.commands wants to drop them too so we will do it eventually

[NyCodeGHG]

A workaround for multi line arguments would be when you execute the command like:

/edit-tag kotlin

Then the bot asks you for the updated text and you have 5 minutes to send it into the current channel.

Is it possible to use Argument#optional() in slash commands? not sure if we need that, but would be nice for user mentions

[DRSchlaubi]

it is just don't do anything after asSLashArgument
