- Ensure presence of FSSubjugationistRace and FSSupremacistRace arcology member variables during BC.
- Improve typechecking for races.

- Restore relative reaction text that was being discarded.
- Discard slave now discards the slave instead of redirecting to Sell Slave.  Bugged slaves can now be properly discarded again, and will reimburse the player half the calculated cost, or the minimum slave cost if the cost could not be calculated.
- Use semantic CSS class names in Sell Slave.
- Fix some missing interpolation.
- Refactor slave buyers a little bit to reduce bloat.
- A few other minor fixes.

Move RE Standard Punishment back to Individual Events where it belongs.  Remove some stray returnTos from events.

Don't execute facility reports for nonexistent or empty facilities (we'd just ignore the output anyway).

Fix AE NCS penalty color.  Skip AE NCS penalty if the slave has giant assets anyway (for instance, through implants).
