Installation:

Create a new Dashboard widget using the "Inline PHP Code" type and past in this code. Place the widget in your Dashboard.

Modified to look for string (ERROR instead of newlines. Some error messages contain several lines, thus the original widget code often didn't actually reflect the number of errors.
