Frontend: pridavanie botov v lobby

Hostitel prida na volne sedadlo bota (+ Bot = heuristika, + AI bot =
natrenovana siet) alebo bota odoberie; boti maju vlastnu ikonu a flag
is_bot v rosteroch. Surove ucty bot:<kind>-<n> sa vsade zobrazuju cez
displayName ako "Bot 2" / "AI bot 1" (stol, kopka, tabulky, historia).
