# Perl
- Add `$client->CampAllBots()`.
- Add `$client->CampAllBots(class_id)`.

# Lua
- Add `client:CampAllBots()`.
- Add `client:CampAllBots(class_id)`.

# Notes
- Adds constants for `NO_CLASS` which is class `0` and uses `RACE_DOUG_0` for any spots that use race ID `0`.
- Cleans up magic number usage of race/class of `0`.
