Package Manager should warn about duplicate packages
Currently it is possible to use the same package key multiple times within the Packages/* directories, for example:
Packages/ Application/ Blog/ Framework/ Shared/ Blog/
The behavior is undefined. We should throw an exception instead to warn about multiple occurrences of a package key.
[+FEATURE] FLOW3 (Package): Duplicate packages are now detected and an exception is thrown, resolves #3950.

Just a note for the future:
It should be possible to have multiple versions of a package installed. Depending on the context the right package would be chosen. E.g:
Packages/ Application/ Blog/ Development/ Blog/
That way you could test new versions of packages before making them available in production context.
Though - until this is implemented, we really should forbid multiple installations.
