Bug 8895 - Warning in systempreferences.pl: Use of uninitialized value in length...

Clicking on Local use tab in system preferences results in warning in log file:

systempreferences.pl: Use of uninitialized value in length at (...)/admin/systempreferences.pl line 456

Reason: content field "value" in table "systempreferences" can be NULL (and is tested for length).

Added test for "defined" at to places.

Thanks for fixing my typo! I did not test by building packages
etc, but by grepping for "Communnity". The patch removes
all occurences of the typo.
