Fix typo in breadcrumb_classes setting

[lennart]

This pull-request will sanitize the option value accepted by the theme setting breadcrumb_classes by removing the trailing space.

I know this is not backwards compatibly, but please think about adjusting your last change to a more sane option-value. Maybe one could run a migration on updating the theme, but I am not that much into maintaining Drupal Modules. If you can lead the way, I am happy to integrate a simple migration that fixes existing database values as well.

The two commits fix the theme settings admin pane (theme-settings.php) and the interpretation of the value inside template.php

Best regards and keep up the good work,

Lennart

Thanks @lennart ! @hyperboy can you take a look at this pull request when you have a chance?

Risk is that a page template is checking using an if/then statement using the existing value and it would not recognize the new value.

We would need to make sure to support backwards compatibility on this, so probably not merging right now.

Because of our hosting ecosystem which does automatic theme updates, we have to have a backwards compatible solution. :/ Tabled for a potential future release..
