Added additional power generation configuration (#1164)
 * Can now configure heat generator power from adjacent lava
 * Can now configure heat generator power from the nether
 * Wind power is now configured by specifying minimal and maximal Y levels and generation values.
    * Defaults to 60J/t at Y 24 and 480J/t at Y 255
Fixed some Electric Chest bugs

Electric Chest was not updating when it was (un)locked, meaning that
mechanical pipes would not (dis)connect and reconnect.

Also noticed that Electric Chest won't accept transporters connecting to
the bottom, which I thought was odd, however it looked intentional so I
left it alone. (..?)

Also made it so electric chests will not open if there is a solid block
above them.
Allow top/bottom to interact with charging slot

Might add side configuration and ejectors and stuff later, but fixes #1281. (Sorry it took so long.)
Stop pipes connecting to front of Heat Generator.
Prevents Mechanical Pipes connecting to the front (energy output) side of the Heat Generator.
Currently they physically connect, leading you to assume they are
transferring the lava, however they are not as this is the energy output
side and it does not accept lava.
