Adding a theme based on twitter bootstrap not using frames

This commit adds a bootstrap 3 powered theme to Sami that does not use frames.

Closes #119, #122, #47, #13, #123.

This pull request adds a new theme that is completely rewritten to be simpler, not use frames, and is now responsive (i.e., looks good on a phone). I've re-implemented the left-navigation using a much simpler approach, created a new search implementation that allows users to hook in custom search result types by extending the theme, and added breadcrumbs. I tried to keep a relatively similar look and feel to the existing Sami theme, but with a bit of twitter bootstrap on top.

Because this provides the same features of the default theme and includes additional features, I would recommend making this the default theme and removing the "enhanced" theme. If you'd like me to do this, then let me know and I'll rebase with those changes.

Here are some screenshots and descriptions of what they do.

Namespaces
----

This is the namespaces page. It just lists each namespace. This is also the homepage if a project has classes.

Here is is at a smaller width:

Note: the button at the top provides a drop down containing the menu.

Classes
-----

Here is the "classes" page, full-screen.

And again, small screen:

Note: Traits, and interfaces look that same as this page.

Index page (doc-index)
----

This looks good on a phone too:

Interface
----

Here's an interface page. Just like with class and namespace pages, the left-nav is scrolled down to show the currently selected node.

Here are the start of the methods:

Namespace page
----

Here's a namespace page. It lists the sub-namespaces, the classes, traits, interfaces, etc.

Search page
-----

When you submit a search query, it takes you to this page.

![screen shot 2014-08-27 at 9 12 57 pm](https://cloud.githubusercontent.com/assets/190930/4071078/a481571e-2e69-11e4-80a6-b02d2d923474.png)

The search looks through the names of each thing in the search index. The search index contains each namespace, class, interface, trait, and methods from each of these.
