Cosmetics + Jammer now in green + Jitter

Browse source 
I think the Jammer deserves a green icon, since it actually does it job pretty well.

Then there is a Jitter parameter. It allows to introduce a jitter from 1/60th of a second up to 60/60th of a second (a full one). It will delay / move forward either the TX or the cooldown period for a maximum of a half of the time you choose as jitter.

Meaning: If I choose 60/60th, a full second of jitter, it will produce a random number from 1 to 60.

Then it will calculate jitter = 30 - randomnumber

THen it will "add" that (positive or negative) time to the  time counter for the next jitter change of state.
