Remove martian chance from salesman spawn

[cyberTripping]

yeah, i've been mulling this over for a while, and I guess here's my thoughts on how martians could be more fun now that i am less salty:

• some sort of translator that goes in the headset slot or similar, which just allows hearing spacemen properly (and talking properly, if that's an issue for martians). It might be funny if martians still didn't differentiate between human voices, not because they can't but just because they don't care.
  
  
• natural slots for pockets/ID slot, maybe with some flavortext about how grody and unsubtle it is compared to normal pockets, which don't give storage messages normally. The otherwise lacking storage options a martian has really fuckin hurts, so this would alleviate that a tiny bit while still maybe being flavorful.
  

• The longer a martian is in a round, the better they understand the humans even without their translator. They start like currently, where messages are illegible, but by 1 hour in, only a third or quarter of letters could be dropped, enough that a player could squint and understand the gist of a message unless they get unlucky.
  
  

and additional, less important stuff:

• resprite to make them look fancy?
  
• a couple unique sprites for worn satchels, backpacks, etc?
  
• give martians the rename prompt at the start of a round, since if they don't understand english it's a little silly to have an english derived name
  
• let them ignore floor hazards since they can't wear shoes, maybe give them some amusing allergy to compensate
