* Adds alt attribute with a value of the `mobile-frontend-sitename`
(previously called `mobile-frontend-footer-sitename`). The message was
changed because this affects both the footer and the header's logo.
* Adds a `minerva-footer-logo` class to the logo in footer.mustache in
preparation for changing that element from an h2 to a div. Given caching
issues (old CSS with new HTML; new CSS with old HTML are both
possibilities), we need to do this in two separate deploy cycles.

The data already provided by SkinMustache makes the existing
Minerva code redundant.
* html-after-content functionality equivalent to dataAfterContent value
* Rename license and last modified to have html-minerva prefixes and promote
to top level data object. This allows us to distingusih Minerva values from core
values.
Note: previously the logo used srcset to ship a 1x logo but these
were dropped during the desktop improvements work.
