WIP: Mob Points System

So, this is another approach on that based on what @WildX said.

Well, to be honest, I just got bored. Might eventually rollback to commit 8e398042.

Anyway, this is an approach focused on porting accounts from Legacy to Evol. I did a marker at Aidan script of where a really deprecated code begins, along two possible suggestions to clean it up.

The “catch” of this code is that it doesn't rewards players solely from porting their accounts. They must kill monsters on Evol, thus gaining Mob Points, to be able to exchange these points for rares (we could add other common drop, money, and even experience on the mix).

I did not bothered with the reward part, as you can probably see. Nor am I providing any merge script (although Moubootaur Legends server have a merge script which was used to port Land Of Fire accounts, and a copy can be provided upon request).

Again, I downgraded this MR to “only a concept” level. I'm waiting your feedback.

This is very similar to TMW-2 implementation of Aidan and Ishi, with minor changes to fit Evol better.

It was tested in the other server to prevent submitting a buggy MR, but additional testing to Evol could be a good idea.
