Wok's Tunnel driller

1.5 Update. Checked interactive destruction. Unfortunately blocks no longer break the same. Needs more work.

Update: added grinder drillbit sprite.
Update:slowed drill unit driving speed, edited terrain.
Update again: Added "intelligent" hazard lights (only on when needed!), changed time truck waits while drill offloads.

This is why I'd like spikes to damage textured pixels: tunnelling.
The tipper on the right goes and collects at set intervals, pausing the driller only while taking on debris.

Note, absorbers don't absorb textured pixel debris, so it gets laggy - which is why the tipper will only have time for three runs.
