Disambiguation rework

[AMDmi3]

Currently we disambiguate projects by adding a suffix to the name (magpie → magpie-ndp-proxy), but the suffix can be long and is limited by [a-z-] used in project names. We can do better by instead providing a separate package field for human readable description, while project name can be appended with a shorter numeric suffix (such as ?1).

Apart from being able to provide readable clarification and format it flexibly (e.g. be able to wrap, trim and popup it), this also allows to change it freely and that won't lead to project moves.
