inflationCancellation fixes

Fixes for a smaller problem I noticed while investigating # 5649: interslave inflation was not being properly adjusted when the harvest dropped, and half the text was missing anyway.

Changes made

• Copied the introductory sentence of slave-slave inflation cancellation so that it displays at all levels of inflation, not just at 8 liters.
• Added a few commas where appropriate, through an admittedly less graceful sentence split (if only addToLast() worked with string arrays, or join() with SpacedTextAccumulators!)
• Added code to actually reduce/deflate slave-slave inflation, which seemed to have been entirely forgotten when the function was originally written.
• Highlighted inflation reductions in yellow, same as full deflations. It's a change to the physical regimen the player assigned, which should be called out, even if it's a smaller change than full deflation.
• Applied all of the above (except the commas) to inflationCancellation in prInflation as well.
• Unrelated minor proofreading in electiveSurgery.

Things left to do

• code review (this is done by one or more people other than you)
• final tests
• let Pregmodder know that this is ready for merging
