Use bower for the site

- updated Twitter Bootstrap to 2.3.2 (required small popover change)
- updated jQuery to 1.10
- used bower for dep management

`git grep assets/jq` didn't yield any results except for the front page

As single commit to allow for emergency reverts. :)

clarify legend on home page by restyling

style "Maroon" in the legend like the labs items it refers to

make the legend stand apart from the list more

and refactor the .labs-example styles

The `<b>` element is perfectly legitimate here: http://www.whatwg.org/specs/web-apps/current-work/multipage/text-level-semantics.html#the-b-element . I am making the '*'s stand out more without conveying extra importance or alternate voice or mood.

style legend with a grey border

to show that it's a different type of content from the lists above

also changed from a `div` with `p`s to a `ul`, as that matches semantics more closely

move legend under the first app list

and remove grey border around legend, since the legend is prominent enough now without it

done at request of https://github.com/tastejs/todomvc/pull/675#issuecomment-23901896

Should fix #677

remove 'order' attribute from comment

fix Meteor description by adding missing space

don't mention 'order' as a default attribute since the attribute no longer exists

Update todoEscape.js

I think you meant escape :)

TodoMVC Mozart example

Unit tests for Flight example

Upgraded to flight 1.0.4 which removed `Component#bind` in favor of the native
or polyfilled `Function#bind` and used the new require.js bower format.

Waiting for @phuu to upgrade to Flight 1.1. :)

use fetch({reset:true}) for 2x-5x increase in processing performance for backbone.

It wasn't used anyways and it's nicer to have no dependencies on the vanilla app.

Closes #654

todo display right padding fix

todo display whitespace fix

currently an item data stored with multiple whitespace in-between words is rendered as having only one space. putting css `white-space: pre` fixes this.

a long todo item might step on the X sign. `padding-right` of 60 fixes this symmetrically (X sign width 40px, right offset 10).
