quickCorrections [Ready to merge]

I could not resist the urge to further cut away at V.activeSlave sooner rather than later and found a few minor issues.

In addition to the minor corrections this MR it's name also included is:

• Small scale remove/replacement of V.activeSlave to keep what little sanity I have left at the moment.
• Minor cleanup (e.g. src/uncategorized/nonRandomEvent.tw has $activeSlave = 0 and $mercRomeo = 1 twice for no seemingly obvious reason). Hopefully coding past midnight has not created too many obvious issues.

What is the point of imageChoice here?
