Refactoring.
Omnibar and edit item dialog addition changes:
* Go to note/task edit dialog from omnibar
* Go to added note's/task's destination (url & swiper slide) from edit dialog. Destination priority order is due > parent > tag
* Pass active note/task as a $rootScope parameter
* Public DateService methods to set initial week and active date
* DatesController init sets initial date slide active if found
