Add breadcrumbs across the dashboard

[Andy Doan (doanac)]

issue 1: http://91.189.93.71:8000/smoke/precise/run/2427/image/2427/ - use build number instead of date in the crumb. while you are in there you can also change the page title to include variant, arch, and type

[Andy Doan (doanac)]

I think we missed some stuff earlier: capitalize the first letter of:
827 + "upgrade details"
884 + "task details",
909 + "task details",
993 + "detailed view",
1201 + "machine upgrade results",
1256 + "machine upgrade details",
1591 + "image {build_number}"

+lava_server.bread_crumbs
+========================
+
+Bread crumb management for LAVA server.
+
+This system allows one to construct static trees of views or even site maps,
+where each view has at most one parent. In this model any view could be
+followed back through the parent link to create a bread crumb trail of named
+URLs.
+
+It is important to emphasize that this system is STATIC, that is, it is not
+based on browsing history. Regardless on how the user got to a particular view
+the bread crumb system will report the same set of pages. The idea is not to
+let users go back (that's the what the browser allows them to do) but to put
+the current page into context of where it "belongs".
+
+To use this system apply the @BreadCrumb(name, parent=parent_view,
+needs=['required', 'keywords']) decorator to your view function. To render
+breadcrumbs you can use the default template that is a part of
+"layout/content.html" template. Your context must include the bread_crumb_trail
+variable. To construct it call BreadCrumbTrail.leading_to(your_view_name, ...)
+passing any of  the keyword arguments specified in needs of your and any parent
+views (yes this is annoying).
+
+A mistake in pairing 'needs' to keywords passed to BreadCrumbTrail.leading_to()
+will result in logged warnings (either a name of the URL being not
+constructible). To fix that simply add the missing keyword argument and reload.
