Miscellaneous borer/bughunt fixes. (#7930)

Borers no longer get teleported out of a host if they're manually removed after leaving the host.
    Removed synaptizine from borer chems. Added dylovene, kelotane, norepinephrine instead.
    You can now call ERTs on Bughunt.
    Borers no longer have nutrition loss.
