feat: Completely ignore clan in friends tab

[kaitlynia]

Scope:

1. Add tc_friends_clear_clan
2. Don't add clan text to config when adding a friend with a clan
3. Don't show clan text in friends tab (shouldn't, if it never gets there)
4. Span only 2 lines, showing name + map (more compact friends list)

I would also be fine with a fully compact friends list that only shows the name, no skin no map just the name, purely functional list

Rationale:
Some people (me) simply don't care about clans and don't want joke clans writing to the config when adding a friend at any time. As it is, if I wanted to maintain a large friends list without clans, I would have to write a simple script to clear clans, which is a bit silly
