Add a hard mat. requirement to Industrial Space Armor

[rulib]

As it stands, with the present revision of the materials system, Industrial Space Armor is able to be fabricated from round start at any of the several (Mining, Mining station, QM, maintenance, etc.) mining fabricators.  Half the crew ends up wearing it at all times and thus looking identical.  It has significantly altered the metagame by making it no longer suspicious to be wearing full-face-and-body armor, as a large cross section of the crew who goes off-station, to maint, or boogies under the QM flaps is wearing the same full-face helmet regardless of job.  It is essentially the universal disguise.

This could be solved by adding a temporary hard requirement of bohrum or uqill (like the cerenkite for cerenkite power cells) until the materials system once again functions in such a way that the issue can be handled with a more generic solution.
