Fixes #10: Arrays can only contain objects, "simple" values won't work

Aside from this fix, arrays, but really the processing of rules (json2tss) has been refactored.
From here on this last step is being performed recursively on values that represent an array or object. This way arrays and special values further down the hierarchy are processed as well.

+ Fixed bug that screwed up when multiple array-values existed
