Thieves Pluggin For UltraVip

The thief must be behind the targeted player, and sneaking. Right-clicking with those conditions on the player will open his inventory as a chest.
There, the thief can steal any item one by one. Each item steal has a probability of success.
If the player fails to steal the item, the target will recieve a notification.
Each stealing attempts will add the item value to a gauge. If the gauge is filled, the thief cannot steal the player anymore on this attempt. The gauge's capacity increases with the thief's level.
Each successful stealing will add the item's value to the thief's experience.
If the thief gets seen by either the victim or by other players within a range defined in the settings, he will get stunned for a configurable amount of time.

The stealing probability of an item is calculated with the formula :
probability = 100 * ( 1 - item value * enchantment multiplier / ( thief level + 9 ) )

where enchantment multiplier = 1 + ( number of enchantments + sum of enchantments' levels ) * enchantment unit multiplier

The required experience to get to a level is calculated with the formula :
exp required = ceiling( 100 * ( 1.6681 ^ ( level - 1 ) ) )

The total experience of a player is the sum of the values of every items the thief have stolen so far.
