manifest: add support for groups in include

Attrib groups can now be added to manifest include, thus
all projects in an included manifest file can easily be tagged
with a group without modifying all projects in that manifest file.

Include groups will add and recurse, meaning included manifest
projects will carry all parent includes. Intentionally, no support
added for group remove, to keep complexity down.

Group handling for projects is untouched, meaning a group set on
a project will still append to whatever was or was not inherited
in parent manifest includes, resulting in union of groups inherited
and set for the project itself.

Test: manual multi-level manifest include structure, in serial and parallel,
      with different groups set on init
Test: added unit tests to cover the inheritance
