Single-click generation of ingestion steps (source->STG->PSA)

[RoelantVos]

A lot of the more standard ingestion mappings can be automated further. This is often done separately from TEAM, but can just as well be done there.

For example, creating a source data object can pre-fill the staging and PSA.

Or, importing a number of sources can automatically create SRC-STG and STG-PSA mappings.
