Allow compression to be turned off

Per report on the Yii site there seem to be some problems on PostgreSQL. I've added a $compressData-toggle that allows to turn of the gzcompress/gzuncompress process completely.

Small bugfix

Just a minor bugfix, but we should keep things up to date right?

Trail functionality available as a separate grid

On request the trail functionality was separated from the generic request logging functionality. If you have generic logging enabled, it will still auto-link the trail records to the request, but it's not longer a requirement.
We also added a new gridview to look at the trail entries.

Minor bugfixing

Fixed a bug in the viewer where it was still using the wrong relation.

Added translation

• The module now correctly registers a translation source with the application if needed.
• Auditing functionality no longer requires request logging to work.

Fixes to stop clashing with built in functionality

The getErrors() function of AuditEntry matches name with the validation functionality causing PHP strict errors because of the incompatible declaration. Renamed the function

Marked as stable

Marked as stable version for people preferring "minimum-stability: stable" in composer.
