Update for Odyssey

Update for 1.6

Reduced underground conduit cost to be more in line with new vanilla one.

Carbon tiles are slower to build and easer to clean (uses new stat).

Update for 1.5.4033

Tagged as 1.4 compatible (no changes necessary).

Tagged as 1.3 compatible (no changes necessary).

* A lot of defs are renamed to avoid mod collisions. It would cause some issues on existing saves (would have to rebuild everything done with diamonds and recreate relevant bills) but it was overdue.
* Diamond renamed to synthdiamond, which is now described as a plastic that looks kinda like a diamond.
* C-composite walls now can be built on weak soil (same as wood now), synthdiamond walls need solid ground like stone.
* Very minor stats adjustments.

Floor tiles are now considered fine for royalty and are a bit more expensive.

Added experimental buried version of electric conduit. Useful when you want to hide them from sight - or from harm.
