Security Option for Timers Enancements

[roger1818]

I was surprised that when selecting either
the Dusk or Dawn modes on a timer, the
Security option becomes disabled.  I would
like to be able to use the Security option
on Dusk timers so that my lights don't
always turn on in the same order at night
(or at the same time several nights in a
row).

I would also like to be able to set the
security range for timers.  Currently it is
hard coded at +/- 30 minutes from the
scheduled time.  I would like to be able to
change it to something else (say +/- 15
minutes).
