Comment 2 for bug 1965985

The skip link was also reported in bug 1744629.

I've created a branch to handle the redundant alt text for icons and book covers: https://git.evergreen-ils.org/?p=working/Evergreen.git;a=shortlog;h=refs/heads/user/sleary/1965985-opac-format-icon-alt

This is just a partial fix for the issues listed in this bug; I have not addressed issues of document flow and navigation in this branch. Note that bug 2015153 is also related to landmark/heading navigation problems.
