Moved processed metrics computation to DataTableGenericFilter, removed new filters & implemented as methods in Report to avoid confusion regarding re-use, allow adding processed metrics as DataTable metadata and use this to rewrite AddProcessedMetrics filter, correct name of Metrics::getMappingFromIdToName function, added placeholder AggregatedMetric class for future, revise Metric/ProcessedMetric hierarchy (add methods for translation/etc.), allow .get API methods to use metadata to automatically figure out which columns to select, get EcommerceOrderWithItemsTest to pass.

refs #5940 moved files into a subfolder framework, added autoloader to remove duplicated code to load autoload.php and to be able to register more autoloaders (eg for test files) on demand. This I got read of many includes that had to be updated all the time and that had to be updated all the time when moving iles

refs #5940 put tests in correct folders, better testsuite names, some tests still fail and I cannot figure out why

Refs #5800, add namespaces to integration tests in root folder. Also add IntegrationTestCase to a namespace, re-add individual test @groups, move test groups to class level, and rename test files & class names so underscores are not used.

Piwik is a free/libre analytics platform. Refs #4455 GNU Package requirement to use free/libre instead of open source

refs #4564 added db update (version number needs to be changed later probably) and renamed more methods

refs #4564 introducing some more new methods for has superuser access. Old methods will still work but are marked as deprecated and they will be removed in a future release

Added namespaces to functions.php files in the five plugins that had one
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.
