Changed Download logs to download the logs currently being shown, not always the current logs - note, doesn't filter first.

Removed "delete" case in logs.php
Moved logging check out of case statements to avoid duplication.
Changed wording of clear logs warning.
Pretty-print the JSON on log export - requires PHP 5.4.
