IScroll scroller in containers with accordion:
 * scroll to opened accordion item and focused add item... input field
 * changed iscroll.js to iscroll-probe.js to get the current scroll position
 * public swipeNext and swipePrevious methods in SwiperService
 * optional scope.disableSwiper parameter in swiperContainerDirective to initially disable swiping in slides with scroller
 * accordionTitleDirective calls refresh scroller (and scroll to element) methdod in accordionDirective after toggle to recalculate container height
 * register focused add item... element to scrollToDirective and scroll to focused element after new item addition
 * initialize scrollToItems scope variable in ng-repeats and watch its size changes to refresh scroller height
 * fire scrollerIncludeContentLoaded on ng-include onload events and refresh scroller
 * scrollToContainerDirective to register scrollers within same feature
 * scrollTo<Top|Bottom>Edge directives for generic pull to next/previous loaders
Fixed bug with last vertical slides inside ng-repeats swiping to undesired slides: changed scope.$last comparison to use attrs.scrollToBottomEdge.
Fixed a bug with last slide rubber band effect: bottom edge loader -adjusted rubber band threshold takes only effect in last slide with loader element.
Fixed broken html which caused loading animation to not show
Added label to prevent default exceptions on iScroll to make checkbox work again on ANdroid
Prevent horizontal swipe by setting onlyExternal swiper parameter true when iScroll is scrolling slide vertically. Not pretty.
Removed refreshing of scroller on feature change and removed scroll-to-container as it was unnecessary without feature change refreshing
Removed setting of home heading from feature container directive - done now locally at NavbarController where it is needed.
Moved current heading updating to HeaderController - faster as digest is only done to header, not the whole DOM on slide change
Removed unnecessary initialization of swipers, fixed HeaderController not setting the right heading sometimes.
Fixed edit page breaking for 'edit context' heading
Renamed 'dates' slide to 'timeline'
Fixed task date edit opening by default on accordion open
Removed erroneus max length for note
Moved titles in full edit to text areas for easier editing
Updated accordion title also to textarea to allow for easier long title editing
Fixed crashes because expanding text area was not cleaned properly on destroy
Bold title for context and list
Scroll fixes:
 * IScroll scroller into all swiper slides
 * refreshScrollerAndScrollToFocusedAddElement callback function to add <item>... submit functions
 * removed scrollToItems list watchers from scrollToDirective
Cleanup:
* removed deprecated touch and scroll event listeners from swiperContainerDirective
* deleted swiperClickDirective and replaced swiper-click with ng-click in DOM
