Refactoring.
Fixed details swiper slide width when only one detail slide exists:
* Set width to 100% for .swiper-container, .swiper-wrapper and .swiper-slide.
White background color for drawer menu's active feature link.
Date slides:
* set initial date slide on init, otherwise swipe to slide with animation
* today button set today slide active without animation
Redirect to appropriate view after item addition from omnibar:
* clear initial swiper slide path from memory after it has been set as a swiper parameter
