Increased creature limit

EDIT: TOP POST BELONGS TO LOOBINEX NOW

Changes:

• Creature limit raised from 256, to 1024, effective limit from 255 to 1022.
• Introduced configurable rule 'MapCreatureLimit`, can be modified on the fly.
• Standard rule has 1000 as a limit, original campaign and everything else with classic/legacy remains at 255
• When mapmaker reduces the limit mid map, the excess creatures leave or die (depending on portal access)
• Raised battle limit from 48 to 192
• By keeping the limit below 1023, fixed issues with growing up(demonspawn) and transforming into skeleton/ghost at limit
• Graveyards and Portals will pause creature generation until space is available
• Failing to create imps at map limit no longer costs money
• Spawn traps failing to spawn retain their charge
• Cleaned up log errors that would occur at creature limit
• Added console command to see the contents of the pool: !map.pool [creaturetype] to get how many of a type are in the portal.

back to you ben:

Prepared for evaluation. This is the code for a rule in the rules.cfg named 'Creatures_Count = 1028'.
You have the option to reduce the number of creatures below this value in the rule.cfg. This rule applies to all players, including Imps, with 1028 being the maximum allowed.
I have conducted tests with multiply creatures and creature transfers without encountering any issues. The Scavenger does not exceed the limit from the pool. However, the graveyard functionality has not been tested."
Side note: While there don't appear to be any pathfinding issues, teleporting a thousand creatures simultaneously may lead to performance issues. It is important for every mapmaker to ensure that their configurations are optimized for high performance, even on less powerful PCs. that will change with the per Player rule in the future.

the code changes in [src/console_cmd.c] are to be able to show the amount of creatures in the pool with a console command. i don't know if that would need a seperate alpha.

and the show pool is minor enough that doing it in this one is fine
