[PATCH] ob-gnuplot: handle remote input files

[Ferdinand Pieper]

When passing a remote file like "/ssh:myserver:/myfile.txt" to a gnuplot block 
as variable the gnuplot process can not access the remote data.

An example:

--8<---------------cut here---------------start------------->8---
#+begin_src gnuplot :var data="/ssh:myserver:/myfile.txt"
plot data u 1:2
#+end_src
--8<---------------cut here---------------end--------------->8---

Attached is a patch, which instead downloads remote files to a unique path and 
passes this new path to gnuplot.

Please let me know if there's something to improve regarding the commit message 
or patch formatting.

Best,
