Enable/Disable entry delay while in stay mode

The option "Entry delay" in StausBits original version delays an entrance alarm if the system is armed in both Away and Stay status. This may be desired for some.

Some users may want an alarm to immediately alert if an entrance is triggered while they are home and armed in Stay mode, rather than wait on a delay (home invasion occurring?).  At the same time they still want the alarm to use an entrance delay when they are returning home while it is armed in Away mode.

This pull request adds a user configurable option to enable/disable entry delay while armed in stay mode.  It also adds a visible status indicating an entry delay is being used if entry delay is configured greater than 0 and weather it is delayed for Away or both Away and Stay modes.

On trigger:
If (<i>zone is an entrance</i> <B>AND</B> <i>entry delay is enabled</i> <B>AND</B> <i>not armed in Stay mode</i>) <B>OR</B> (<i>zone is entrance</i> <B>AND</B> <i>entry delay is enabled</i> <B>AND</B> <i>armed in Stay mode</i> <B>AND</B> <i>EntryDelayStay is enabled</i>) <B>Then</B> Delay Alarm by xx seconds;  <B>Otherwise</B> sound alarm immediately.
