makeJScallback removal

This PR:

• Makes initial state use selection widgets
• Fixes toggleable widgets being always active
• Optimizes histogramming
• Slows down histoTable - it's redrawn every time any histogram changes, not just once per selection change - can only be really fixed by making dependency trees on client, before this change behavior was incorrect
