Added links to tags.
Changed to haml-rails.

Because of templates.
Generated site scaffolding
Added spec to demonstrate Site feature functionality.
FakeWeb will now serve a second example page.
Added routing for sites.
View lists bookmarks for a site.
Site model knows about the association with bookmarks.
Site index should display links as titles of sites.
Reddit URL didn't match FakeWeb registered URI.
Site title should be fetched from root of domain.
Extract functionality from Bookmark.

This functionality is needed in Site model as well.  It now exists in a
service object to assist both models.
Cleaned this spec a bit.

The default rspec controller template doesn't behave well with Rails4's
new parameter filtering.
Expect site URLs to have proper scheme.
Rename domain column to url.

This brings the behavior of the Site model in line with the Bookmark
model.
Bookmark should use full URL for models.
Use Rails 4-style params for controller.
Render site titles in index.
