move {silent} to /autoresponder add to support pre-made embeds, buttons, etc.#815

this is in regards to the new variable introducted in v8.17.1 !

currently, {silent} is a variable form that allows us to shut off and customize ar errors. however in its current state adding pre-made embeds to it doesnt work since it’s nested. to further expand the customization {silent} provides i suggest to move the variable entirely to the slash command /autoresponder add so it can support pre-made stuff (if it works that way, in any case?) for example:

/autoresponder add trigger: TRIGGER reply: REPLY matchmode: exact silent: <custom msg>
(where if left alone, it’ll display the default error, type “yes” to silent, and use any variables in that field to attach buttons or pre-made embeds)

additionally i think this would be the closest we could get to creating if-then scenarios with autoresponders :3
