Add a fetch refspec to fetch tags from a Radicle remote. The --no-tag option is also included. This is to ensure that it is easy to collaborate by having tags placed in the remote namespace of another peer. However, if the namespace is the default rad remote, then tags are expected to be allowed – this is to pave way for the feature of canonical tags.

In the tests, the --tags option is removed – and is generally recommended that it is not used. This is to ensure that it does not override the --no-tag option.

Changes:

• removed rogue emacs files
