Fixing issues with holographic outline cache in AllApps/Customize.

- Fixing issue where the outline cache was not properly used when changing orientations
- Making the outline cache static, and shared across both the AllApps/Customize (since they
  share an Apps view)
- Making sure that holographic outlines for items on only one page are not created, since
  the holographic outlines will never be shown in that case.
- No longer clearing outline cache as frequently
