Rehashed Item_delay.txt (bugreport:5487)

- Before you could only have MAX_ITEMDELAYS (10) items with delays. Now: you can have up to MAX_ITEMDELAYS (10) concurrent delays. and of course you can always increase MAX_ITEMDELAYS in src/map/itemdb.h as much as you may need.
- Item delays are no longer lost on logout, they're persistent until server restarts.
- When a item use is denied due to delay still up a message now tells the user why he can't use the item (before would leave the user wondering wtf was going on. it had no response)
