Dusty

* **New**
* Added `dusty doctor` command to attempt to fix some common VirtualBox networking problems
* Added a custom 502 page for apps which use host forwarding. This lets you see the status and logs of your container while you're waiting for its HTTP service to come online
* **Misc**
* Implemented a [networking fix](https://github.com/docker/machine/pull/3112) the Dusty team implemented in Docker Machine within Dusty
* The daemon now raises its open file handle limit to 8192, which should prevent some OSErrors during parallelized Git operations

* **Breaking**
* Dusty app and lib spec filenames must now abide by Docker image naming conventions: `[a-z0-9]+(?:[._-][a-z0-9]+)*`. Your file name must start with a number or lowercase letter, cannot have uppercase letters, and can only have `.`, `_`, and `-` as special characters.
* Dusty requires Docker Machine 0.5.0+
* **New**
* Added `dusty shutdown` command to shut down Dusty's virtual machine
* Added `--only` flag to `bundles activate` which makes it easier to turn on a selection of bundles and deactivate all others
* Added support for SCP style GitHub urls. Example: gitgithub.com:gamechanger/dusty.git
* Added `image_requires_login` key to specs which can specify Docker images to pull. If set, Dusty will make sure the user is logged in to this image's repository before trying to pull the image
* Optimized the `up` and `test` flows for some significant performance gains
* Dusty now shows the progress of image pulls on `dusty up`
* **Misc**
* Added support for Docker Compose 1.6
* `dusty disk restore` now appends the `dusty-backup` suffix to the restore path if not provided, which should make the `restore` command a bit more intuitive to use
* Host forwarding now supports multiple forwarding rules per app to the same container port for HTTP forwarding
* Fixed a bug where intermediate containers were not removed when creating testing images
* Revived a previous networking fix that was removed after Dusty moved to Docker Machine. This fix improves external networking performance by up to 50% for large file transfers.
* Fixed a case sensitive bug between HFS and NFS.

* **Misc**
* Dusty now recognizes if the SSH agent socket path has changed on each command and resets the value if necessary
* Dusty is now compatible with recent versions of `docker-machine env` by passing the `--shell` flag

* **Misc**
* Added support for Docker 1.9 following breaking changes to the default Docker bridge IP.
* Test images are now automatically rebuilt when repos they depend on have new commits.
* Fixed a bug which could prevent tests without `once` commands from running correctly.

* **New**
* Dusty can now forward arbitrary TCP connections (for example, SSH) through to running containers by specifying a `type: stream` key as part of `host_forwarding` configuration in app specs. See the [SSH server app spec](https://github.com/gamechanger/dusty-example-specs/blob/master/apps/sshServer.yml) for an example.
