- new subcommand: linkpac, to create a linked package

- extend edit_meta() with two arguments: template=new_package_templ, change_is_required=True
- increase BLOCKSIZE in othermethods.putfile() (1024 seemed a little small)
- extend othermethods.putfile() to serve a string buffer instead of a real file 
- for filelists, don't read _meta file any longer (depracated). Read directly
  from /source/<project>/
