Title: Changed cell_deleted to on_cell_deleted, allowed returning false to...

...prevent deletion.

```ruby
def on_cell_deleted(cell)
if cell[:arguments][:some_value] == "something"
App.alert "Sorry, can't delete that row."
false
else
RemoteObject.delete_remotely
# return anything *but* false to allow deletion
end
end
```
