Manipulator: expose matrix, scale & flags via RNA

Merge branch '28' into custom-manipulators

Manipulator: rename struct members

Rename:
- matrix -> matrix_basis
- user_scale -> scale_basis
- scale -> scale_final

Match RNA names being added to custom-manipulator branch.

Eevee: Put pack AO parameters.
