New po diff view

[Claude Paroz <claude 2xlibre net>]

Dear translators,

You may have noticed a new icon right to the PO file download button.
That new link (only available if there are fuzzy string) shows an HTML
representation of the po file including inlined diffs for strings having
the previous string (#| msgid...).

For me, this is especially useful in documentation where strings are
often multiline and where it's not easy to detect what exactly has
changed. Of course, you may use a PO editor that already provides this
functionality, in that case you can ignore that new icon.

Hope this helps some of you.

Regards,

Claude
