String change in Cheese documentation

["Leonardo F. Fontenelle" <leonardof gnome org>]

IIRC I didn't need to, but I wanted to tell you that I introduced minor
changes in the documentation for Cheese:

http://svn.gnome.org/viewvc/cheese?view=revision&revision=1177

Updating the translation should be trivial for the 5 or 6 locales for
which the documentation was completely translated before.
