Add the missing removeTodo method to the sample.
Add a guide on the router flow when a user clicks on a link-to

Update computed-properties-and-aggregate-data.md

A code example of an array being filtered when the array only has one example is not terribly interesting (and probably doesn't get the point across as much). My suggestion is to make the example a little more interesting, while keeping it relatively simple still.

[website] [master] Resolver logging on debug page

Fixes that we don't mention the better logging that @rljackson added for default resolver.
Relates to: https://github.com/emberjs/ember.js/pull/4655
and also, was mentioning it in this discussion and realised it wasn't present in the debug section: http://discuss.emberjs.com/t/nested-resources-and-dynamic-segments/5111/4
Adjust with comments from rjackson
[website] fix missing desc. on getting started

This PR fixes #1499. Adds in an explicit description to remove the `selected` class from the "all" link.
Update toggle-todo-editing-state.md

Adding more details to prevent misplacing the code. Since "isEditing: false" is followed by a comma, this piece of code must be added before "isCompleted:...".
Improve doc for routing error event
Rearrange content based on event substate as main section
Add a section about the replace option of link-to
Using newer method for DS.RESTAdapter customization.
Added check to see if todo input is blank

Without this check if you hit enter on a blank input it would throw a typeerror
Fix for visual sidebar glitch on builds page

There are two divs on this page using the same id of "content"

<div id="content-wrapper">
    <div id="content">
        <!--outlet-->
        <div id="sidebar"></div>
        <div id="content"></div>
        <!--/outlet-->
    </div>
</div>

This causes a CSS glitch on the sidebar menu. Referencing the other pages it seems this external "content" div is not needed and removing fixes the CSS glitch.
