The python version should allow us to remove any ruby dependencies and should also slightly speed up dokku installation. All LSB-compliant distributions should have python, so we should be okay depending upon it.
Closes#1783Closes#1786
The version of docker.io in jessie-backports is 1.6.2~dfsg1-1~bpo8+1.
This is regarded as lower than 1.6.2 by dpkg because `~` has a special meaning
in regards to version sort in dpkg.
This leads to:
```
The following packages have unmet dependencies:
dokku : Depends: docker-engine-cs but it is not installable or
docker-engine but it is not installable or
lxc-docker (>= 1.6.2) but it is not installable or
docker.io (>= 1.6.2) but 1.6.2~dfsg1-1~bpo8+1 is to be installed
Recommends: herokuish but it is not going to be installed
```
By changing the contraints the version in backports will be accepted by dpkg.
Changing the herokuish package to Recommends instead of Depends allows users to skip the installation of that package by specifying --no-install-recommends. Herokuish will still be installed by default using apt-get
* 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.
