Edit and delete buttons need descriptive alt text

[Jono M]

To be accessible to screen readers, all images and image-like elements need an alt attribute specified. One area where this is not the case is edit and delete buttons.

- In the Journal, Delete buttons have a title attribute but no alt attribute (they need both)
- Notes is the same
- Delete buttons in Resume composite forms have alt="[x]" which should be changed to something more descriptive
- Manage tasks buttons in Plans use a missing string for alt text
- Edit and Delete buttons in group Forums have no alt attribute specified (same in Topics)

Ideally most of these should include the name of the thing to be edited/deleted in the alt text, eg. "Edit 'My plan'", since sometimes the editing buttons appear above the name of the thing to be deleted (in the HTML source) and sometimes they appear below.

Edit and Delete buttons should now have consistent, descriptive alt text -
where possible this includes the title of the object to be edited or deleted

With this patch, the forum topics page looks broken for me.

I can replicate the problem on Chrome (doesn't happen on Firefox). Thanks for letting me know, I'll get a fix out ASAP

Fixed display of edit and delete buttons (Bug #1276397)

The previous patch for this bug caused miniature text to be overlaid on
buttons in the list of forum topics. Adding text-align: left fixes it
