* Replaced jA's way of allocating npc shop data with a simple dynamic array that gets allocated during loading and freed on unload

Browse Source 
- automatically fixes bugreport:404, which would otherwise require manipulating the npcname_db (the original author didn't, hence the bug)
- now a supporting variable 'count' is used for tracking the length instead of an extra dummy entry at the end of the shop list
- partially removed the MAX_SHOPITEM restriction (if this was written properly, the system could support an unlimited amount of entries)
