HALO Changes

- Blacklisted apps don't show in HALO while scrolling
  * Blacklisted icons are visible in status bar but are skipped
    when scrolling through HALO

- Added count for total number of unique notifications in HALO
  * Total count is visible when HALO is idle / disappears while hidden or tasking
  * Total count ignores pinned apps, blacklisted apps and persistent notifications

- Added new icons for pinned apps and persistent notifications

- Set a standard distance between message markers for HALO
  * Notification markers no longer spread out on larger screens
  * Distance between markers will be reduced if necessary to accomodate multiple notifications

- Notification dismissal sync
  * When a notifcation is launched via HALO, it is cleared immediately from the bubble
    the next most recently received notification takes it place in HALO
  * If a notification is cleared via the notification shade, either from the status bar or the PIE menu,
    the notification is automatically removed form HALO

- HALO will ping on screen unlock ONLY if active notificaitons exist, under the followng conditions
  * Status bar is hidden and HALO is hidden (Expanded Desktop Mode/Hide HALO after activity)
  * Protected lock screen is enabled - The android notification ticker does not "tick" when
    using a protected lock screen HALO usually does not update while the phone is locked
