Provide tools for analyzing a p2 aggregator model's constituent parts

Refactor metadata repository representation to make it reusable in the
analzyer model's editor.

Provide better progress reporting on repository loading.

Do artifact mirroring in parallel. Compute sha-256 if those are missing.
Avoid saving the artifacts.jar repeatedly while mirroring. Produce also
the *.xz versions.

Do the verifications in parallel.

Provide support for opening *.aggrcon which opens the corresponding
*.aggr and selects the contribution in that editor.

Support additional things such as expand all, collapse all, revert.
Eliminate child creation icons.
