* [Zones] Add Max Level Check to Zones.
# Perl
- Add `$client->CanEnterZone(zone_short_name)`.
- Add `$client->CanEnterZone(zone_short_name, instance_version)`.
# Lua
- Add `client:CanEnterZone(zone_short_name)`.
- Add `client:CanEnterZone(zone_short_name, instance_version)`.
# Notes
- Allows operators to limit zones to a maximum level.
- Allows operators to see if a player can enter a zone before sending them.
- Keeps players from entering via `#peqzone` and `#zone` as well if they do not meet the requirements or are not high enough status to bypass the requirements.
