Mod for Remote controlled items: radio cars, radio bombs, radio electronics

Hello. This is my first expirience with git and my first pull request to Cataclysm DDA.

About mod:

+ Box with radio car and remote control (I think, this box must be placed in some shops, ideal for kid's shops).

After unpacking box you gain:
+ Radio car. This item can ride and managed by remote control. Also radio cars can be charged with radio bombs.
+ Remote control. Has joystick to manage radio car and several button, that send several signals to receivers.

For example I added:
+ Smart lamp. It like flashlight, but can be turned on/off via second button on remote control. 

For modders: look on .json, this example show how simply add any object activated remotely (no source code needed, just json-modding).

+ Two remotely activated bombs and recipes for them (from dynamite and pipe-bomb) . Also very simple json, can be exploited.

Bombs can be inserted to radio cars.
