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?

* Author name field in copyright transfer form separated to first/middle/last name, I changed view, controller and DAO to display proper fields and retrieve their value from database. In our internal db there's only single 'authorName' column in table with copyright transfers, so we agreed with Krzysiek that at the moment we can store concatenated first, middle and last name in this column.
