Project Mode: Moving Content in the tree or media gadget

Description

Moving content in the site structure will not associate the content or its children with the current project since the move operation is immediate and thus requires no publishing. In order to make this more obvious for the editor the warning text shown in the confirmation dialog when moving content has been updated to explain that the operation will occur immediately and that the operation can have an impact on SEO since the URLs of public content will be changed. If project mode is active then an additional message is appended stating that the content will not be associated with the project.
