Changing bot tags and other tags on Fluxer

The bot is called "system" which may confuse others for "bots" and "system dms"

Add a simple text placement for others to change it from "system/bot" to something like "clankers" or "robots." Alongside different tags for stuff like "Staff" or "Bug Finder," already seen the Premium but we could give it icons to redo so it's not just "Fluxer" icons specifically since some of them may not match aesthetic or it's not the branding that said self-hosted instance wants. (Originally like my "brand changing" but the suggestions look like they're going through better, thought to do a remake of it) (somewhat satire, but also good idea)

The App Identity could be the place where you can change specific icons like "Staff" and "Premium," possibly "Bug Hunter" and whichever has a logo for user badges into something that can differentiate from the original Fluxer look, so that owners and admins of self-hosted instances can give different logos for each.
