* Bump `Version` field.
* Set minimum nginx version to 1.4.6, per #1654
* Depend on both `rubygem-foo` (Ubuntu) and `ruby-foo` (Debian).
* Add distro-default `docker.io (>= 1.6.2)` as an alternative.
Version 1.6.2 is in both `trusty-updates` and `jessie-backports`,
while `trusty` itself has `0.9.1`. We seriously want to avoid that.
This also updates the docs so people don't forget to bump the version
field in the future. Even though we really do that for them with sed.
This will allow developers to run an `upgrade` on existing installations without breaking because docker-engine isn't yet in their apt lists...

We had an issue with third party plugins installing things via apt while
already installing dokku itself via apt.
To resolve this, `plugins-install` and `plugins-install-dependencies`
now can take a `--core` flag allowing to execute the install hook only
on core plugins and not on third party plugins.
Another feature with this modification is the ability to disable/enable
plugins. Two new commands now exist:
* `plugins:enable <name>` to enable a previously disabled plugin
* `plugins:disable <name>` to disable an installed plugin. This won’t
work on core plugins.
This should allow installation of the dokku packages on debian jessie. Upstream docker created this package in response to an issue where `cgroup-bin` could not be installed at the same time as lxc.

This reverts commit 1bf30bdcb1.
Commit was reverted as this breaks installs of core plugins. It is also a hack around broken plugins that don't use the `dependencies` pluginhook.
All core plugins that require debian packages already have those packages specified in the `depends` stanza of the `control` file, so no need to respecify them here.
