Ion Cannon

This mod adds small and large block variants of a Star Wars-stye Ion Cannon, to let you temporarily disable "functional" blocks on your enemies (or friends, if you prefer.)

The projectile doesn't deal damage to grids, although it will certainly hurt you if you're in the way. When it hits, however, it will affect any active blocks within a radius (about 20m for the small version, 50m for the large version.) All affected blocks will turn off for a few seconds, then back on again in sequence starting with the ones furthest from the impact point. Any blocks which are not active (i.e. turned off) when the projectile hits will NOT be affected.

Obviously the ability to disable other grids is a pretty significant advantage in combat, so these are a few balancing methods I've included:
* Gun fires quite slowly, and area-of-effect is limited. The large block will keep a section of grid "locked down" (i.e. inactive) if continuously fired at, but not the whole of large grids.
* Simultaneous hits from multiple guns do NOT add time nor range to the effect.
* 300m/s speed for the projectile, not super-fast.

Should give some lighting effects to impacted blocks, and tested OK on dedicated servers.

Massive thanks go out to BruceCarcharias for putting the model together for me.

MAINTENANCE NOTE: The 1.181 update which brought multithreaded physics to the game, also brought massive performance drops on my systems. The continuous stream of minor updates and hotfixes since has done nothing to improve performance over 1.180.600, and have solved less issues than they have caused. My own server has been reverted (via subscribing to the 1.180 Beta) to the stable, smooth and enjoyable experience SE gave me back then, and as this mod works well with this reversion I have no plans to keep it maintained for broken later versions.
Please don't use comments below to engage in criticism of the game, and the best of luck to the Keen developers who hopefully will eventually give us the SE experience we all hope for. I'll continue to read comments and respond when I can.
Apologies if this decision affects your enjoyment of the game.
