Packaging

[nyov]

A simple packaging to start with, for issue #2

I took the liberty of renaming the project in this one from my suggestion in #5, will amend if necessary. A license file is still missing, as I'm not sure yet if we go with MPL1.1 or 2.0 here now? Or just (L)GPL?

This is a commit on top of PR #6.

Hi!

• Can we save the rename for when we actually have non-decrypting features in here?
• Make target "dev-install" is not marked .PHONY by mistake I suppose?
• Let's not restrict README.rst by re-use from setup.py. That one should be free to evolve freely.
• Let's make "Mozilla® Firefox® / Iceweasel, Thunderbird® / Icedove, SeaMonkey® / Iceape, and others" a list with one item each line. That resolves the reading ambiguity which of those is Mozilla officially, and which is not.
• The VERSION file could be version.py instead to be * imported by setup.py and * used by cli.py passing to ArgumentParser for --version
• Please remove commented-out code
• .. and rebase against master.

Best, Sebastian
