Added a constructor that allows us to be a drop-in replacement for

our superclass and implement a reasonable toString() so that if
setLogTimers() is enabled, our timers will at least have reasonable output.
Swing's own timers will still be cryptically logged like so:
"Timer ringing: javax.swing.Timer@12022b7"
