Material datum functionality changed to mimic that of reagents etc. by
using a global datum list and an assoc value list.
Material datums added at the atom level.
starting_materials var added - on New(), the materials in the list are
added to a datum. An empty list generates an empty datum, a null means no
datum.
m_amt, g_amt, and where applicable gold_amt, etc. completely removed,
replaced with starting_materials where applicable.
Fabricators
Fixed a bug with fabricators taking design cost, not shown cost.
Fixed a bug with fabricators taking costs before a design was shown
completable.
Fabricators now transfer the materials they use in the design to the atom
produced's material datum.
Designs are now world-consistent : scanning the same atom will ref the
same design, and scanning an atom with a design will fetch it.
Mechanic fabs now add plastic cost on top of the design, not to it.
Mechanic designs no longer require random extra materials.
Mechanic designs are now material-specific, not type-specific.
Mechanic blueprint uses have been removed, in favour of a consumable
system.
RnD wires moved to the datum system.
Autolathe moved under fabricators. It preserves as much functionality as
possible.
Framework added for plastic costs on mechanic fabs to be toggled, and for
removal of designs to be toggled also.
The drop_item arg is now the loc placed, not the child of the loc or whatever.
Removed a few lines of items being placed into themselves, on themselves, into other things manually, into their users, etc.
Cleans up the fix for MoMMI recharger silliness.
This took about 2 hours of non-stop manual searches.
Breakable. Spill contents on breaking or hitting the solid stuff after being thrown.
Have limited capacity. Can be emptied in disposal outlet.
Change sprite when are half-filled and filled.
Also fiddled a bit with the cigs code, so you can put them out without dropping.
