Show statistics related to notes disable/enable in admin/dashboard

[GoogleCodeExporter]

Since now the author of record can disable/enable notes for a record, we can 
use the logs of these actions and show some statistics of them in dashboard.

This is very related to issue 77, 78 and 82. So try not to work on these issues 
separately/in parellel.

To view the admin/dashboard page:
http://china.personfinder-dev.appspot.com/admin/dashboard

Place to start:
app/admin_dashboard.py
app/model.py (UserActionLog class)
app/confirm_disable_notes.py
app/confirm_enable_notes.py
