[archive] Allow archives in any directory
Current code will create an archive in the current directory with:

    % archive ../test.tar.gz test.*

or will complain that the following archive doesn't exist in the current
directory (given it actually exists in the parent one):

    % unarchive ../test.tar.gz

Fix that and allow archives in any directory.

Other changes:

* Use `<required_param>` instead of `[required_param]` in the usage text
* Don't explictly check if archive exists in `unarchive`, but let the
  respective tool fail with its own message

Closes #312
