FW: LS Notifications Rewrite add notification logic & fix pokect mode

Original commit message:

 There were some problems with notifications getting replaced while the user was currently dragging them.
 This commit should fix that by always waiting until animations and user input are finished before replacing a notification view.

and I added some missing line for pocket mode fixes
