Upgrading ng-grid JS and CSS to the latest HEAD of the 2.0.8 branch (1ee01f4f)
Added delete button to bracket view.

Also fixed newScope.destroy() bug in ng-grid, and fixed newViewportHeight calculation in ng-grid-flexible-height.js so the bracket list table won't get a scroll bar.
Fixed bug in bracket list where new bracket was added to the table multiple times.

Also changed server code to re-calculate total points for the bracket, every time the points for the round is recalculated.
