Two new buttons added from suggestion one of my D&D group players had:
- Clear all dice inside zone
- Clear all dice outside zone

Dice now reset position based on rotation, as long as rotation is 90 degrees.

onLoad() now calls removeMissingGUIDs() to remove invalid IDs from the dice_guid table. This should fix issues of importing the tile into new tables retaining saved data.

removeMissingGUIDs() now also checks to see if the object it contains is also a dice object. If not, it will remove it from table.

clearAllDice() now also checks to see if the object is a dice object, if it isn't it will not destroy the object.

Corrected error in script throwing errors for import into new table with existing values.
