'--non-recursive' argument is not stripped in project's build definition if project was added to an existing project group with 'For multi-module project, load only root as recursive build' selected

The '--non-recursive' argument is removed from the project group build definition if the project was added as a group pom (project group is defined from POM).

Fixed in trunk -r985992 with the following changes:

• add a default project level build definition with '--non-recursive' flag stripped if adding a multi-module project as a single Continuum project to an existing project group
• added test + docs

This has a problem - it created a project level build definition every time you add a project (even with a new group). Working on simplifying the process to only do that if it differs from the group.

refactored the code a bit to be clearer about when it is added

• when creating the group at the same time, the group definition is edited instead
• when using an existing group, the project definition is created if the group one has different arguments
