Required fixes in order to avoid the bot detector

[NadavTarago]

1. Randomization of waiting time (sleeping time) -

2. Randomization of list element selection -

3. Skip each x element. x should be randomized, between 2 - 7 (2 means one added :** Not implied yet - every few elements should be ignored. (Don't send connection request).
   as in each iteration those skipped one would be added again - should find a way to avoid the re-adding.

• [ V] Randomization of waiting time (sleeping time) -

I did it by chosing random range of ms, create the function getRandomInt.

• [ V] 2. Randomization of list element selection.

I did it by converting the nodeList into array, create the function getRandomInt. Now the code chose random card in the array by its length.
