Add support for external pipelines using project files

- Support loading external pipelines as templates with project files
- Add template files for some standard pipelines
- Remove the hard-coded generation of new pipelines
- Update multiviewPipeline test: the multiviewPipeline test relied on the hard-coded generation of
pipelines.
