Updating HACKING file

I've removed libzeromq-perl
and added libterm-progressbar-perl, libfile-copy-recursive-perl,
and libjson-perl.
We should define a way to install ZeroMQ module on Debian stable.
I've installed it via cpan, but before I've needed to install:
$ apt-get install libzmq1 libzmq-dev uuid-dev
Digest::SHA1 is deprecated in favor of Digest::SHA
One dependency per line
