Made fires be garbage collected and not hard deleted on demand.

Committing for S0ldi3rKr4s0 (I hate your name).

Fixes some typos in blueprints.dm, designs.dm, dna_mutations.dm, gift_wrappaper.dm and research.dm.
Gives minerborg some eyes to signify activity (finally)
Made pAI cards need only programming 2.
