Latest round of changes.

• Staff now come with a static skill stat and no longer level up - this stat is now out of a 100 instead of 25 in order to introduce more management reasons there.
  
• Owner firepower added to Muscle Rating. That shotgun under the counter now means something.
  
• Fixed the nemesis spawn rate on the non-asshole town setting (more assholes spawn now).
  
• Sheriff suspicion multiplier added once they roll into town - it now becomes harder to get away with things once the Sheriff is there.
  
• Premade Saloon floor plans have now been added. Two for now, more to come.
  
• As requested, edge map scroll and left-click map scroll added - player no longer has to use the keyboard to move their view around the map.
  
• Stair fixes.
  
• Numerous fixes to the build system. Jankiness reduction continues.
  
• Saloon stock can no longer fall below 0.
  
• Can no longer delete upper floor if occupied. No more floating cowboys.
  
• Optimized late-game performance.
  
• Events added for pig pet, theater, and sheriff.
  
• Can no longer duel, murder, frame, or propose to sheriff.
  
• Start date changed to 1861 to account for event text.
  
• Kitchen animations adjusted to account for spoons in pots.
  

There's a bunch more that I'm not thinking of.

Thanks as always to player for the feedback and reviews - more to come.
