TODO: Optional desktop alert when glucose crosses a threshold.

[Delubear]

Add config setting DesktopAlertThreshold Value of 0 means disabled, otherwise it takes a glucose number (same format/conversion logic as the existing glucose numbers that support MG/MMoL) When glucose goes from below this number to >= to this number, show desktop alert with message.

[Delubear]

First implementation will most likely be:

• Alert when reaching Warning High, High, Warning Low, and Low
• MessageBox.Show() when reaching critical low
• Settings option for enabling/disabling each alert (most likely an Alert column to the right of the value input with checkboxes)

[Delubear]

Implemented as of version 11.0.0
