BPE information while importing and in release overview

[Walter.Koller]

Currently during the import process about non information is available, like target groups or what are the items causing conflict.

It would be great to have some type of preview window showing the contained items and structure similar to what is available in Releases tab. 

Also nice would be the creation date of the package being part of the release file. Currently the 'create' date shown in Releases tab is the date assigned by the local client, either date of creation when creating a new package or the date of import. This means when moving a release to another environment the creation date of the package there will be different to the creation date of the originating environment. It would make more sense to have creation / modify date static as part of the release and maybe add another column (eg release date) for when the package was last imported/exported.
