Add taskjuggler ruby gem (2nd try)

This time I've verified that "gem nix" didn't produce any gems with
sha256 = "no hash". Hopefully nothing else breaks :-)

Thanks to phreedom and shlevy on IRC for the tip about removing
~/.gem/nix-sha256.cache to fix/workaround the "no hash" issue.

linux-3.10: remove the btrfs send patch

it helps, but is incomplete.
more fixes are coming, but including these would change too much
generic btrfs code, which might cause trouble for others.

so the best advice is not to use btrfs send yet and wait for 3.11 or 3.12
