Character keeper updates

I've been doing some work on character keepers lately, and today I took some time to implement some of what I've learned in the Shepherds keeper.  New things include:

• The Rising Star is now selectable as a Story
• Improvements to the layout of the Safety tab
• Character creation questions are now listed below advances, with some space to fill them in. These auto-populate when you select a Story
• All auto-populating fields on the Character tab now display as blank (instead of "N/A") if there being no Story selected
• There are now two dropdowns on the GM Sheet: XP Cost, and Trust Value.  These come preset to 8 and 6, respectively, but you can change them, and it will update the values in End of Session and Grow Closer, as well as the highlighting of XP (if you have enough to Advance) and Trust (If you have enough to Grow Closer)
• Sadly, the above change results in the loss of the italics for the triggers in End of Session and Grow Closer, hopefully that's acceptable.

Hopefully these features are useful!

"Scenario 2" is still in development, but it's a toughie. I'm expecting there will be another, smaller one first.
