Clean up HAML.

- Add haml-lint config file to allow long lines. This is temporary
until I can find a HAML syntax highlighter that supports splitting
attributes on multiple lines.

- Clean up HAML to make haml-lint pass

- Convert application layout to HAML

- Fix bug that caused google translate initialization to time out. The
JS was looking for an ID called `google-translate-element`, but in the
layout it was called `google_translate_element`.

- Make description meta attribute localizable.
Move common partials to shared folder.

The Rails convention is to keep partials that are shared across all
pages inside either the `layouts` folder, or in a `shared` folder. I
prefer `shared` because it’s more explicit.

I also fixed the >IE8 conditional at the top of the application layout.

Clean up HAML.
Enable raise_on_missing_translations.

Since we’re using internationalization, we want to know if we’re
missing any translations, so the settings should be enabled in both the
development and test environments.

Fixes #547 - geolocation button disabled state

Geolocation button still appeared clickable after an error. This commit
adds styles to override the hover state when the `disabled` attribute
is present on the button. It also performs some cleanup of the
geolocation-action script by:
- Formatting and adding additional code comments.
- Moving the geolocation button content to a variable.
- Moving the disable/enable content of the geolocation button to its
own functions.

It also adds the ability to re-run the geolocation check after an error
so the user can re-check for geolocation if they had a temporary
connection failure that prevented geolocation for the first check.
