check if function exists

if you use foundationpress with a child theme, you get an error.

PHP Fatal error: Cannot redeclare foundationpress_breadcrumb()

Hi. Can not merge as the test have failed. There seems to be 45 errors in navigation.php. Could you fix the errors and push a new commit? https://travis-ci.org/olefredrik/FoundationPress/jobs/72619330#L225

@Stevie-Ray PSR-2 violations, easily fixed if you just follow the messages. This would be very useful to get this pulled in as it causes some issues if you where to copy it from parent to child.

We noticed an alternative fix would be for you just to create a library/navigation.php file within your child theme and use that in addition to parent for new declarations. Our use shows that wordpress will still use both and not overwrite one or the other. Since of course functions only exist in parent and not child.

It seems to work ok now
