Tar action, multiple actions on cli and rename release dir

[tsloughter]

Multiple actions can now be specificed for a relx run. Example, $ relx release tar, this will generate the release and then a tarball of the release.

With this change it is now the case that $ relx relup will not generate a release first. You must run $ relx release relup in order to both generate the release and then the relup, if you want to do it all at once.

Additionally, in order to adhere to the systools and release_handler release spec the output for a release is now to releases/ instead of releases/-

Argh, ignore for now. Forgot to update the tests.

Ready to be reviewed and merged.

The second change, do you mean the adding tar? Because I added tar before adding the multiple actions support. But because I then made a lot of additions to fix up tar support it would not be a clean/clear separation to make.

I fixed up one of the worst offenders of going over 80 chars. But I wish we didn't have to live with such an archaic limit :P

Its not archaic at all. The perfect example if this is 'tsloughter@a168263'. Long lines destroy the ability to use the interface. Its the same on my emacs. If you have long lines I can only look at one file at a time. Where if we stick to something reasonable like 80 chars I can have multiple columns up and compare them in the same screen. I guess if you where using something much more limited (which is really everything but vim and emacs) it wouldn't matter. Thats not the case for me and I don't think its the case for most people.
