Title: Issue 1405

Input and animation lag was occurring because bindEventToGradeEntry() was being called for every mutation of the subtree of "#content" on the spreadsheet. This fixes the issue by adding a flag that is checked before calling bindEventToGradeEntry(), so bindEventToGradeEntry() is only called when needed. Tested on Firefox and Chrome
