Hello Guix,

The patch bellow adds TorBrowser, Obfs4 and related libraries. No
more warnings, it should behave as expected. User files are
stored under '~/.local/share/torbrowser'.

Just two notes: 
- some of the libraries do not have a named font and just claim
  BDS-Style. I've written bsd-2 for those and left a note. I'm
  no sure if there is need for a more appropriate description.
- https-everywhere does not show rules on the browser, but the
  rules are there on the store path. There is no default address
  for autoupdating rules.

And one important question: tor and obfs4 are inputs to torbrowser
which are symlinked in the install phase. Do they need to be
propagated so as to not be garbage collected?

Happy Hacking!
