Math: lots of tweaks. See #1083

Browse Source 
- Initial calculation performed once - changed binding to either "filterEnd"
  or "pagerComplete", not both.
- Added change flag so a cache update is only performed when cell content
  inside of a sortable tbody was modified.
- Fix data-math-filter on "all" cell calculation with fixes to getRow &
  getColumn functions so that filters get priority over the "filtered" row
  check.
