tagadelic 6.x-1.1

Two bugfixes in this new release.
No new features are introduced, though it is still a good idea to test thoroughly before upgrading.

#286666 by nburles. Add default array() to the return of tags.
Thatt way we always return something.
Good coding practice and solves several foreach-warnings.

#227910 by jgoldberg. Fixing an eronous array key, that broke the block caching.
