Radio buttons used when importing need labels

[Jono M]

For people using screen readers, having a label for every form input is essential as they have no other (easy) way of knowing what the input is for. When importing a Leap2A archive, the "Ignore" and "Add new" radio buttons don't use the <label> tag.
These should really specify what they mean (what is being ignored or added) using hidden text so that screen reader users don't have to navigate around to find out.

Made radio buttons in import accessible (Bug #1278238)

Linked to labels, added hidden text to labels describing what will be added/ignored/etc.

Also made links only show for items that actually have hidden information
to show to avoid confusion when clicking on the links.
