Adds a large ash and large molten item decal (for future use)
simplifies decal/cleanable/replace_decal() code a bit.
Changes construction() proc to on_construction() for consistency, same for deconstruction().
Made a deconstruct() proc for machinery and computer (also for future use).
Added two new materials, Titanium and plastitanium. Titanium is naturally occuring, and plastitanium is an alloy made of plasma and titanium.
These materials can be used to build shuttle walls and floors, though this serves no current purpose.
Before you yell "SNOWFLAKE" about the materials, I have definite planned purposes for them, not to mention what else they could be potentially used for (mechs, R&D, etc.)
You can use titanium to make white shuttle walls that smooth (like the ones of the escape shuttle), and plastitanium to make the grey syndie shuttle walls. You can also make floor tiles out of each material for the different shuttle floors. This PR itself doesn't change any of the paths on the map to use smoothed shuttlewalls and I'll save that for a seperate PR.
Also this PR makes ORM code better and allows people to easily add new alloys

Makes the ore redemptor machine 100000% less spammy to request consoles, and prints a list of what exactly is in the machine. The new non-spamminess means chemistry and the bar can now get a notification, because there will only be one message per load.
Adds bluespace polycrystals, basically a "smelted" "sheet" of bluespace crystals, to the game, in order to make the ore redemptor accept them.
