Bug 27496: Accessibility: Navigation buttons are poorly described by screen readers
This patch adds aria-haspopup and aria-expanded attributes to the language
and welcome user buttons so that screen readers will know that they cause a
popup menu to be displayed.
To test:
1. Use an installation with at least 2 active languages
2. Log in the OPAC
3. Use a screen reader (e.g. ChromeVox in Chrome) and use the tab key to
navigate to the language and welcome user buttons while noticing that
they are described as "Button collapsed" and "Button", respectively
4. Alternatively, inspect the buttons and notice that they are missing
aria-haspopup and aria-expanded attributes
5. Apply the patch
6. Observe that these buttons now are described as "Popup button collapsed"
or that they contain the aria-haspopup and aria-expanded attributes like
the lists button
7. Sign off
