Job details page shows the job id, fixed bug

Job details page now shows the id number for the current job, reading it
from the URL using the RequestParser
Fixed a bug where if no query string was provided (index.php was
accessed directly) then a blank pagename was used (instead of 'home') and an
exception was thrown.
