string change in yelp

[Matthew East]

Hi,

Just to let you know, I've submitted a patch which has been accepted
which changes one string in yelp - the phrase "desktop effects" is
amended to "visual effects". This is important to ensure consistency
with the current phrasing in the visual effects UI preferences.

It doesn't affect documentation but translators please take note so
that the new string can be translated.
