Alt-tab - Reduce the spread delay for all items other than the initial item the select lands on after alt-tab opens

Bug Description

Reduce the spread delay for all items other than the initial item the select lands on after alt-tab opens. After the user moves the select off it's opening position, spread delay should be shortened. This change is because a longer spread delay is only required for the initial item to allow the user time to scan the items in alt-tab without being disrupted. The spread delay on all other item can be shorter, which should give a more responsive feel.

----------------------------------
Note from User Testing:

In user testing, participants did not find the spread because they moved between applications too quickly. When I pointed out the spread to them, they commented that the delay was too long. Power users said that it would be faster for them to find what they were looking for without the spread.

-------

Note: Re-opening bug because user testing has shown us that the spread delay needs to be shortened even further.

Have you already tested the desired timeout?

@andyrock, as discussed, this change created bigger issues. Please revert the delay value to what it was in Precise. Sorry for the hassle.
