Now sending 'precacheend' event only once.
Now sending progress events only when not already CACHED.
The timer date/times are now updated before the layer is precached (when adding a second animated layer).
Clearing cache and parent div on moveTo, so that progress etc is calculated properly and so tiles are rendered in the correct place.
Deleted some dead code.
Hooked up animation download button.
Animation download button is always visible.
Refactored time format.  Deleted commented out code.
Renamed MomentComboBox to TimeComboBox, in preparation for changing how values are stored.
Using JsonStore.
Storing date values as unix time (so that they can be matched in the store).
Using local times.
