* Fixes for E_NOTICE in workqueue: - introduced class `Friendica\Util\Arrays` which will hold static methods for handling arrays that cannot be done with PHP's functions, like implode() on multi-dimensional arrays - rewrote old-school for() loop to foreach() * Added intial unit test with some tests on empty delimiters and/or sinle and multi-dim array. * Added test for for 3-dimensional arrays, thanks to nupplaphil's feedback.
