Work in progress

Refs #3781, fixing build, revert last change and add getSuperUserLogin to Piwik_Access (so FakeAccess can mock it). Modified PDFReports to use Piwik::getSuperUserLogin instead of accessing config directly.

Fixes #3781, make sure getUserPreference returns valid default value when option is not set in the DB.
