JClock.setTimeUnit doesn't set initial delay of the timer

[pictavien]

The method JClock.setTimeUnit(int delay) does not update the initial delay of the timer used by the JClock. I suggest to add timer.setInitialDelay(delay).

I applied this and pushed it on branch fix/89-JClock-settimeunit-delay .

Note:

• as far as I can tell, it seems to fix issue #90

• the rare users which use the maximum 3 seconds delay with the JViewer "Set system speed" feature, if unlucky, might experience a maximum 3 seconds delay before noticing the clock speed update.

  In my opinion, it is a small price to pay compared to issue #90 inconvenience.
