Couldn't get release to compile without "dev" classifier.
- Fix server crash when Computercraft computer is placed beside a radar
- Fixed Radar peripheral for ComputerCraft methods always returning "insufficient electricity!"

Essentially, the problem was that the Radar would be given energy, would use the energy and update, and then ComputerCraft would call a method, before more power was given to the Radar.
Now we just mark it as being powered/unpowered during the tick, and the ComputerCraft call will just check that.
- Bug fix: Radar station will now actually show players who have a Signal Disrupter, if the Disrupter is out of power.
- Bug Fix: Client should no longer randomly crash when opening an ICBM GUI while having an updating item in inventory.

This happens because the ICBM GUI screens does not have an inventory, so when the client opens a GUI window locally before the server, and the server tries to update an item in the (now non-existent) player inventory, it crashes.
Now we delay opening the GUI until the server tells us to, but a better fix would probably be to just enable the player inventory in the ICBM GUI's.
Also verify build version when client joins server.
Change: Added setting for how long Short Range Missiles(Fired by Rocker Launcher or Cruise Launcher) should live after being fired.

Previous hard-coded default was for it to live for 16 minutes!!!
Noting that each Missile is a chunk loader, a few stray missiles from Rocket Launchers could easily take down a server.
New default is 10 seconds, and can be changed in config.
- Bug fix: Server side Radar will now be able to detect other Radars placed before it.
The problem was that the radar would drain energy before being checked by other radars.

- Change/Bug fix: EMP Towers will now only show up on Radar if the EMP Tower is fully charged.
- Bug Fix: The Radar will now correctly show entities and tiles on the client independent of client or server view distance. Up to the full 500 block range.
- Bug fix: Signal Disrupter, Radar Gun, Defuser and Laser Designator will now correctly charge on most MJ/RF chargers.
- Bug fix: Due to previous bug fix, the Rocket Launcher recipe is now functional(Requires fully charged Radar Gun).
- Change: To fix the charging bug I had to scale up the max energy for the items, and also scale the cost accordingly. They still have the same amount of uses before needing to recharge.
