Fixes #35: Add watchdog entry at start of creating a snapshot

fixes #35

@robertgarrigos Adding an extra line at 214 doesn't appear to be necessary.

Adding an extra comment to the start of the next hunk may add consistency: // Create watchdog notice for reference.

Otherwise this looks good.

Also, I wonder if the line that is added to watchdog should be changed, removing the for and adding a comma? 'Created snapshot, %filename'

@izmeez how about a colon (:)? ;-)

A colon will be fine.
