made CFG_PATH_GFILE and CFG_PATH_PDFTOTEXT configurable from the environment

[erickpeirson]

In order to containerize refextract for use in a web service, I needed to be able to explicitly specify the location of the pdftotext binary. So I altered refextract/references/config.py slightly so that the environment variables CFG_PATH_GFILE and CFG_PATH_PDFTOTEXT are preferred over shutil.which. This may be relevant for #9.

Coverage increased (+0.009%) to 79.022% when pulling e3efc23 on erickpeirson:master into ec837cb on inspirehep:master.

Woah, someone else is actually using refextract ? Great!

Commit looks ok, except for the commit message. What about

config: make file and pdftotext paths configurable

Makes `CFG_PATH_GFILE` and `CFG_PATH_PDFTOTEXT` configurable
through shell variables, with fallback on the output of `which`,
in order to allow for easier containerization.

That seems like overkill. And it's already "signed off" as I'm the commiter. So, no thanks; but that sounds like a great line for the release notes! :-)

That's the thing, we generate the release notes from the commit messages!

As for the Signed-off-by, eh, we had this debate internally, and we have people on your side and people that like the trailers for things like Co-authored-by to share credits. But ok, I'd rather have your commit than not. Can we compromise on

or even

?

Ping @erickpeirson: if you answer the above I can include the commit in the next release...
