A "tap" now shows the date for three seconds.  This might need to be a
configurable option.
Some fixes to display the date.
Add graphics for warnings.
Updated icons that fit better on the screen.  Also images for success
messages.
Heaps of new code.  This add the following features:

    * Bluetooth disconnection warning (good if you're like me and
      leave your phone behind);
    * Low battery message to indicate low levels; and
    * Response to a tap will show the date.
