Updated to support 0.17.2

Now supports towing depleted asteroids.

Fixed an issue related to game changes.

Note that the hotkey to toggle towing is now F11 instead of F4

Fixed a problem related to change in recent game build.

Towed objects now change color while they are off the grid, such as when they are being towed.
It is now possible to turn off towing even if the object cannot be added to the grid but the color change of the object will remain, until it is towed again and moved to a suitable spot. Note that the color change will NOT persist if you load a save with an object that is off the grid.

Towed portals should function properly now as well as update their icon/labels on the map after they are towed.

The towing beam has been updated, both when operating at full power and when under powered. When under powered the beam will appear red, otherwise it will look similar to how it used to.

Towed objects will now properly snap to the grid.

It is now possible to tow Dyson Platforms, which otherwise can't be moved. Note that any connected structures will not move with it. You will not be prevented from towing the platform too far from the star so use with care so it's still functional.
