Add pages for container and objects

It is now possible to browse individual containers and see details for
the objects.
Ignore auto-generated components
Ignore backup files
Make Karma generate coverage report
List some alternative Swift file managers
Re-enable the default progress output

Otherwise there is no command-line output when running tests.
Ensure trailing slash when browsing a container
Include jQuery

We will use some jQuery utility functions here and there in the
future. AngularJS is compatible with jQuery: it will notice that
jQuery is loaded and return jQuery-wrapped elements instead of using
its own jQuery-lite type.
Let client specify extra parameters when listing objects
Let humanReadable ignore non-numbers

This will be handy since it lets us give pseudo-directories a
non-number size (such as '---') which the filter will let pass through
unchanged.
Browse pseudo-directories

Before, all objects in the container was listed without taking
pseudo-directories into account.

We now traverse the container using prefix and delimiter to let the
user browse the container in a hierarchical fashion.
Compute bread crumbs before listing objects

We don't need to wait until we have queried Swift to show this
information.
Add minimal Bootstrap styling to tables
With Bootstrap, we don't need HTML5 boilerplate CSS

The Bootstrap CSS will do all the resetting needed.
We don't need or use Modernizr right now

I don't plan on using too many fancy features that need feature
detection.
Remove no-js class

This was a left-over from the use of Modernizr (which would replace it
with a "js" class when it detected that the browser supported
JavaScript). We absolutely need JavaScript so the tag is redundant.
Remove IE6 and IE7 specific markup

This was there to add special classes for these browsers. However, the
browsers are practically dead: outside of China, IE6 is used by less
than 1% of the users and IE7 is universally used by less than 1%. See:

  http://theie6countdown.com/
  http://theie7countdown.com/

for details.
Remove IE8 specific markup

I don't plan on doing anything special for IE8 that would require
selecting that browser specifically. The usage of IE8 is about 10%
worldwide, so we should probably still test the site with it:
