Per journal features

* Added directories for each journal, path: public/resources/journalId. Temporarily, each contains the same txt file and logo image. 
* Pdf generator and web view use JournalUtilProvider to retrieve logo ad consent text for specific journal by its id

I'm not sure how we can prepare for situation, when there's no consent and logo for given journal id (see JournalUtilProvider - I assume, that files *always* exist, no FileNotFound exception handling). Is lack of these files even possible in deployed, working system?
