Possible fix for when minecraft refuses to bind to ipv4

Some users were having issues where minecraft would refuse to bind
to ipv4, this is a possible solution to that problem.
Update server to 1.7.10

This commit upgrades the server to 1.7.10. This also means that the
EULA must be accepted for the server to start up. This can be done
manually by editing the `eula.txt` (ew, manually), or by setting the
`node['minecraft']['accept_eula']` attribute to true. We can't
automatically accept EULAs for users, so this is false by default.

* Add attribute for accepting the EULA
* Write out a eula.txt resource with the content based on whether the
  EULA was accepted
* Some minor readme cleanup
