notify: change 'Remove' button to 'Reset to default' for built-ins

A HTTP DELETE for a built-in target/matcher acts as a reset to its
defaults. This patch changes the 'Remove' button text based on the
selected target/matcher. If it is a built-in, the button text is
changed to 'Reset to default'. Also, if the built-in is not actually
modified, the button is disabled.
