Fixed missing icon for phoron items.

Some of the items like phoron sheets were invisible because they linked
to "sheet-phoron" which didn't exist in the items.dmi.  I copied over
baystations items.dmi which fixes this issue without losing anything.

sheet-plasma -> sheet-phoron
sheet-plasmaglass -> sheet-phoronglass
sheet-plasmarglass -> sheet-phoronrglass
coin-plasma -> coin-phoron

adds efundcard icon.

Replaced broken generator with basic PACMAN generator.

I replaced the placeholder portable generator which didn't work at
(97,69,1) with the crappiest portable PACMAN generator that does work.
