Add new PlayerInteractEvent

If the player interacts with a transmitter, it will simply turn on a
channel.
New method in WirelessChannel which allows to temporarily turn it on.

The channel would turn off after a given delay.
Right clicking on a Wireless Transmitter will now use this method
(currently, the delay is 100 ms, but it will be possible to change it in
the config)
Adds InteractTRansmitterTime in the config.

It's the time spent before the channel turns off after turning on
temporarily.
If you find a better anme tell me :)
