[LegendControl-Defender] Protecting legendary pokemon from theft.

Now legendary pokemon appear with a standard chance of 10% and with each unsuccessful attempt to appear, another 5% is added to the chance and so on until the legendary pokemon appears. After the legendary pokemon appears, the chance will be returned to standard.
You can check the chance and the approximate time until the legendary pokemon with the /checkleg command. For players with certain rights, the spawn of possible legendary pokemon will also be shown additionally.
The mod also prevents possible fake appearances of legendary pokemon, and also takes into account the poorly working legend system in the main mod.
