Server loads regen only once after start

[Heathcliff 176]

Hey yoo!

This little thing allows you to make new regen files called: regen_once.txt (you can rename it to anything).
Modification is using an already existing function called: regen_load_in_file, which has been used by quests.
You can use it, to generate some monsters / npcs at the server startup which don't have any respawn time, so if you kill them, they won't appear until a new server restart, or manually reloading your regens if you have those functions.

In common/service.h - Add:

#define ENABLE_REGEN_ONCE

In game/src/sectree_manager.cpp - Search:

			snprintf(szFilename, sizeof(szFilename), "%s/%s/regen.txt", c_pszMapBasePath, szMapName);
			regen_load(szFilename, setting.iIndex, setting.iBaseX, setting.iBaseY);

Add under:

#ifdef ENABLE_REGEN_ONCE
			snprintf(szFilename, sizeof(szFilename), "%s/%s/regen_once.txt", c_pszMapBasePath, szMapName);
			regen_load_in_file(szFilename, setting.iIndex, setting.iBaseX, setting.iBaseY);
#endif

In game/src/regen.cpp - Search:

	snprintf(szFilename, sizeof(szFilename), "%sregen.txt", mbMapDataContainer[lMapIndex]->szBaseName);
	regen_load(szFilename, lMapIndex, mbMapDataContainer[lMapIndex]->base_x, mbMapDataContainer[lMapIndex]->base_y);

Add under:

#ifdef ENABLE_REGEN_ONCE
    snprintf(szFilename, sizeof(szFilename), "%sregen_once.txt", mbMapDataContainer[lMapIndex]->szBaseName);
    regen_load_in_file(szFilename, lMapIndex, mbMapDataContainer[lMapIndex]->base_x, mbMapDataContainer[lMapIndex]->base_y);
#endif

If you done it, you can create regen_once.txt with some mobs, and place it to your map folder next to regen.txt. If you don't place it in every map folder, you will get some syserr that says it can't find regen_once.txt. It won't cause any problem. It just inform you, that you didn't create that file for certain maps.
