Add command presets

[usirin]

Is your feature request related to a problem? Please describe.
I am currently streaming in 2 different channels and one of the most frustrating things is that i don't have the same commands in both of them.

Describe the solution you'd like
Add command presets, let me show you an example:

• I add senchabot to my twitch channel
• I type !acmdpreset kampus
• Then i get predefined commands automatically.

Command preset creation can be done in UI

Additional context
fossabot has presets, but it's more complicated than this. I just want to be able to easily install more than one predefined commands for my channel
