Add abstract implementation for actions
This commit adds the interface `IAction` and the abstract class `AbstractAction` as a base for supporting multiple actions without much effort for implemeting new ones. The current baked-in possibility of moving files from the source to the target directory has been migrated. See e4b3872 See d9b7b2d
