Django-ssh-deployer

This release adds two new options:

* `collectstatic` defaults to `True`; setting to `False` will not run the `collectstatic` command.
* `migrate` defaults to `True`; setting to `False` will not run the `migrate` command.

This release contains a breaking change, but should make deployments more reliable.

* Changes the default to upgrade `pip` after the `venv` is created.
* Installs `wheel` into each `venv` created.

To maintain current behavior, be sure to include `upgrade_pip: False` in your configuration.

* Add option to customize git checkout path.
* To retain the current behavior, set `DEPLOYER_CLONE_DIR_FORMAT = "{name}-{branch}"` in your Django settings.
* Moved release notes to GitHub. Previous release notes are included on the 0.5.0 GitHub release.

Previous Release Notes

Previous release notes are included here, since this is the first release using GitHub release notes.

* Add a `--no-confirm` command line option for publishing without confirmation. Be careful!

* Pipe output from security context switches to /dev/null by default.

* Add `upgrade_pip` option to upgrade pip in the destination venv to the latest version.
