Minor balance changes

Foxes were a bit to squishy, the -2 CON was a bit much as they are also pushed to being mages and other very low hp classes, and without the dex bonus the halflings who also have -CON they just were a bit to fragile. So I shifted the stats a bit. I moved one point from STR to CON so they now have a -2 STR and -1 CON vs -1 STR and -2 CON. 
I also tweaked on of the presets quirks % chance of something happening, but I have not heard anything of anyone even finding her yet so will hold off on details.
