Support Environment Variables in Body File

[jacksgt]

As an enhancement of #14, another nice-to-have feature would be the support of environment variables for the string specifying the response file.

This should open up many convenient use cases.

E.g. ~/test.txt expands to /home/jack/test.txt

But also: $HOME, $TMP, $USER, $PATH, $LANGUAGE ...

Wow, that was quick action! Amazing!

Cool, thanks for the ideas, I've never though about it.
BTW: I saw you were working on asciimoo/wuzz#72 (comment), it would be awesome to get your help on a debian package for httplab too :)

@gchaincl I'll look into it, but since your project isn't a dependency mess, it shouldn't be too hard :-)
Although I can't give you an ETA yet.

Ok, great to hear!, There's no hurries on this.
