#259: Pass p1 to theme and changethe node creation date format to german_date
Whats in the MR:
Added a node preprocess hook in the module file to change the node creation date format to 'german_date' without time for teasers. Also pass the p1 which is main parent of the book in the variables so that it can used in templates.
How to test it:
In the template see if you are recieving date in correct format and p1 is also accessable.
