Adding new configurable protection distance.

This needed to be configurable, I have been getting some complaints and unknown questions from server owners about this. These settings were hard coded and now will no longer be.

In order to enable this in an already running server without losing config start the server up with the new 0.1.6 version and do a /telecom mansave command.

Default Configuration:
"towerProtectionDistance": {
"xDistance": 5,
"yDistance": 20,
"zDistance": 5
}

How it works:
If you set the all the distances to 0 then you may build towers right next to each other just not on the same block. (1 block away)
If you set each distance to 1 then you may not build a tower within 1 block of each tower. (2 Blocks away)

I'm sorry I'm kind of slow, my life is pretty busy. Thanks for hanging in there!
