added basic version of title details activity:
- displays all information (except list of loanables) like in the mockup
- receives the title object through putExtra()
- loads more information (authors, editors, loanables) from the title in the background and publishes them to the view after they are loaded (during the load a loadicon in the actionbar pops up to indicate that data is loaded)

bugfix in the TitleDao.getByIsbn()
