-New carrot in-tray sprites.
-Added define for bottle of adminordrazine and supporting code for injecting
adminordrazine into plants. Basically for debugging, so I don't have to spend 10
minutes injecting plants with mutagen each time.
-Raised the passive species-mutation chance slightly. For real this time.
-Added sprites for red and yellow floorbots into aibots.dmi.
-New PDAs for the botanists and librarian. Sprites for cartridges for both too.
(There's some work into a botany cartridge but it's commented out for now)
