Mob Item Adder

---

This mapflag sets more drops for monsters at the map that it's been attached.

You can set up to ~50 more items for mobs.

"drop_per" is the chance of drop, from 1 (0,01%) to 10000 (100%).

There's an example at the screenshot, I setted a Yggdrasil Berry with 100% of chance for the Poring at prt_fild08 map.

You can set a lot of mobs, but you have to set more mapflags for your maps.

Original mod by @zephyr 

Example:

mapname<TAB>mapflag<TAB>mobitemadder<TAB>mob_id,item_id,drop_per{,item_id,drop_per(...)}

I had to make a number of changes to the script, otherwise it didn't work correctly.

The only problem I have not been able to solve is the duplicate drop if @reloadscript is produced on the server
That is, if you did reloadscript 10 times, the drop will drop in 10 instances.
