Dealing with .linkconfig changes with 0.46.0

[aplteam]

If there is a LINK config file by the name .linkconfig in the project's source folder, any definition in the "LINK" section of the Cider config file is ignored. A message will remind the user to delete the "LINK" section from the Cider config file.

However, with version 0.46.0 this will change slightly: because LINK 4.0 saves stop vectors as well as trace vectors in a file .linkconfig, Cider checks its contents. If the file contains nothing but stop vectors and trace vectors and the LINK version number the file was saved by, Cider will evaluate the section but recommend that the user reconcile the two sources of Link options and eventually delete the LINK section from the Cider config file.

The new documentation needs to be amended accordingly.
