refactor: Collada reorganize class constructors

- Class constructors without body (only attribute initialisations)
  can safely be kept in the class header files

- Constructor variables should be initialized in the order of their
  definition in the header files

This change is also aimed to remove a couple of
build warnings from the linux builds.
