1. Improve consistency between brothel and club advertisement passages.

2. Fix stray HTML tag output in club ads page.
3. Mark Brothel Advertisement, Club Advertisement, and Coursing Association passages as `jump-from-safe`.
4. Fix `cashFormatColor` and `App.UI.DOM.cashFormatColor` so that the invert parameter does what it was originally supposed to (i.e. represents an explicit cost or expense, rather than an income or flux: displaying positive numbers as red, without a negative sign, and negative numbers as green, with a negative sign).  I'm not sure how this turned into "just negate the number"...`forceNeg` does that job just fine.
