This commit adds a placeholder image for Child objects (in the future, hopefully, photo uploads will be added) and reworks the Dashboard view to look better when more than one child is in the database. There are also some minor tweaks to the Child detail view and one new Gulp requirement to improve the flow of copying static image assets from apps.
This commit is intended to improve the mobile experience by updating the timer detail page with the correct, current duration when, for example, a phone is unlocked after having been locked for a while with the timer detail page open.
