Collada exporter update

Added new feature: Collada: global axis rotation upon export (UI)

The new feature allows to specify the target rest coordinate system upon export.
This allows for example to export a character that is in Blender orientation (Y forward)
to match the Secondlife orientation where (-X forward)

- Refactor:Added new utility methods to collada_utils
           Made BCMatrix class more powerfull
           moved Blender related structures into new BlenderContext class
           added class wrapper to encapsulate ExportSettings structure
           Added blender context getters to ExportSettings
           added access methods to BlenderContext into ExportSettings class
           Moved class BCMatrix into BlenderContext
           moved utility functions from collada_util into BlenderContext
           replace own function for parenting by a call to ED_object_parent_set()

- Cleanup: removed obsolete parameters from methods
           renamed parameters for better understanding
           cleanup whitespace and indentation
           removed obsolete comments
