Ghostdrone quality of life improvements + 1 bug report

[Fiddy]

I'm a weirdo who likes to spend the entire round as a ghostdrone. During this time I've stumbled across a few issues and annoyances:

• Currently the only way to start a round as a ghostdrone is to join as an observer and add yourself to the queue. This excludes them from end of round rewards and possibly other things. I think it would be nice to have ghostdrone as a selectable job.
  

• Give ghostdrones a toggleable option to have doors operate as if human i.e. they block you and open automatically if you have access. This will make dragging things across the station much easier.
  

• For gods sake, give ghostdrones chemistry access. That place blows up at least twice a round and I can never get air canisters in there.
  

• Hacking doors is glitchy. Pulsing with the omnitool doesn't work properly and window spam can occur. Unsure how to reproduce consistently, but it seems to be related to lag.
