- Reintroduce cancellable scroll top on page change
- IndexPage: rely on browser to retain scroll position on page reload
- Remove obsolete browser hack
- Fix broken selector
- When on mobile, only retain scroll for IndexPage if we're coming from a discussion
- Move app.cache.scrollTop save into `onbeforeremove` so we make sure to do it before DOM is detached
The default first post number is '1', so we scroll to that if we're calling `m.route.set` without a `near` parameter, as that means we're scrolling to the top.
This was present in beta 13's implementation, but accidentially omitted in 3f0b3c7.
We also remove unnecessary typecasting for simpler logic and increased consistency with beta 13.
The current implementation for checking whether we are on a discussion page, and going to a discussion page, checks the route we are going to. This is problematic, because the route resolver represents the route being considered, not the route we are currently on. So, if we are currently using a DiscussionPageResolver, we must be going to a route handled by DiscussionPage. Instead, we need to check the route that we are currently on, which is done via `app.current.matches(DiscussionPage)`.
- mapRoutes: don't wrap components in resolvers if they are already resolvers
- Extract defaultResolver into its own class
- Allow either route resolver instances, or components with an optional resolverClass which should accept the component and route name in its constructor.
- Introduce a resolver for DiscussionPage, so that routing from one post to another on the same discussion triggers a scroll instead of rerendering
- Add an index to reply placeholder so we can scroll to it directly when replying.
- Stop pretending that the currently broken `bottom` scroll functionality works, and explicitly call it `reply` scrolling to be clearer
- Directly get target from state
- Explicitly scroll to placeholder on reply
- Clean up scrollToItem code a bit
- Account for edge case where index is undefined when scrolling to post

Essentially, whenever a route is loaded, we add a key to that component. If the key changes, the page completely rerenders. Switching between different routes handled by the same key triggers those rerenders.
- If the fadeIn animation is specified on the PostStream class itself, any time we add/remove another animation, it will redo fadeIn. To avoid this, we move fadeIn into it's own css class, which is applied, and then immediately removed after the animation is completed to ensure it only runs once.
- The "fix" for flashItem was actually broken, as it resulted in 'flash' never being removed, so we never went back to .PostStream's fadeIn. We adjust flashItem to ensure that '.flash' is removed. We also remove 'fadeIn' in case it hasn't yet been removed in oncreate.
Make header and navigation components redraw after page components. Page components manipulate the header (state), but the header redraws before the page on route change. By changing the mount order, we change also the redraw order.
