Store player informations with MySQL.

[IzNoGoD]

1. its easy to exploit your database system, just naming myself something with ' will escape your string-input. User input == evil, so treat it as such.
2. You should look into insert...on duplicate key update....
3. You are using the most basic mysql functions, which can cause your server to lagg. Try looking into the async mysql module i inserted into libcod.
4. Can you confirm by using phpmyadmin or heidisql that the changes are actually in the database? if not, your connection to the database might not even exist.

Edit 5. your insert into doesnt specify the guid of the player, which is the primary key of the table and should always be set.
