LDEV-1891: Add an advanced option: monitoring teachers get notified when a student submits an assignment/resource/survey answer.Removed duplicate key names in the database models.
LDEV-1677: Changing the tools so that clicking Close on the authoring confirmation window will both refresh the tool's monitoring window AND take the user back to the current tab on the monitoring window (ie the same tab it was on before it was refreshed). Normally this will be the edit activity tab.
LDEV-1572: Resize charts to allow larger charts when the legend is large. If it looks like the legend will go over 4 or more lines, then it creates a chart 750x550. I've also increased the size of the small chart to 400 square. Moved some of the common code into a utility class so that our sizing is always consistent.
