Bug fixes, map fixes

Changes:
1) General map fixes. Removes the teleporter console off the bridge (it's useless), replaces it with the research/engineering shuttle consoles so the bridge has control over all shuttles. Adds airlocks and a separate lockdown to virology. 
2) Removes the call shuttle option from laptops.
3) Fixes telepathy.
4) Synthetics are now immune to all changeling's stings. Changelings get a warning when they try to sting synthetics.
5) Makes the previously removed ambassador jobs refundable.
6) Fixes holopad speaking.
7) Removes Pingsky's hate for humans, as it's now actually on the map and may interfere with proper threat assessment (and doesn't really do anything useful, aside from adding a number to a declaration).
8) Other bug fixes.
