Tool to manipulate package data

As a developer I want to have a tool to operate package data such as level of "support" using GUI. The tool must track dependencies to prevent orphaning libraries if one or more packages depend on it. The tool should operate on level of bbappend files in the support layer and create patches which can be used in MR for reviews. Related to #387.
