String change in Orca

[Joanmarie Diggs <joanmarie diggs gmail com>]

Hi all.

In the spirit of a more user-friendly Orca Preferences dialog, we've
gotten rid of the string "update interval:", replacing it with
"every". :-)

~~~~~~~~~~
#. Translators: Here 'every' labels a spin button through which a user
can customize the frequency in seconds an announcement should be made.
(The spin button is followed by the label 'seconds'.) Thus if a user
chooses 5 in the spin button, the complete phrase would be 'every 5
seconds'.
#: ../src/orca/orca-setup.glade.h:178
msgid "every"
msgstr ""
~~~~~~~~~~

As always, the Orca team is very grateful for all the work y'all do!

Take care.
