Chances of getting this in Docker

I think I'll take a look at the project and try to build what you mean. :)

@tanzimabir Currently with the admin area I built (#2) it's probably not too difficult to flesh out to have different boards based on giving each a specific url. `e.g. /screen-1, /screen-2` etc.

The PR also includes a RESTful system for sending messages to boards, as such we could adapt this to allow specifying the screen name so you can send to specific boards.

If my PR gets accepted I'm happy to adapt it to add these features as I think they would be useful.

But is your RESTful system also compatible with Home Assistant ?

@Kevkotsu I haven't actively tested, but based on the documentation [here](https://www.home-assistant.io/integrations/rest_command/) it should work with similar config to this in it's current incarnation.

``` yaml
rest_command:
flipoff_set_message:
url: "http://YOUR_FLIPOFF_HOST:8080/api/message"
method: post
content_type: "application/json"
payload: '{"message":"Server driven updates are live"}'

flipoff_clear_message:
url: "http://YOUR_FLIPOFF_HOST:8080/api/message"
method: delete
```

Then call it with

``` yaml
action: rest_command.flipoff_set_message
data:
message: "Dinner is ready"
```

I’ve implemented the multi-display part of this and it’s included in my PR (#2)

FlipOff now supports multiple boards, each with its own set of screens. Boards can be served from their own route using `/board-slug`, and one board can be marked as the default so it appears at `/`.

The API now supports targeting a specific board with `boardSlug`, and manual screens can also be targeted directly with `boardSlug + screenSlug`.

For Home Assistant, the call can now look like this for a specific board:

```yaml
rest_command:
flipoff_send_message:
url: "http://YOUR_FLIPOFF_HOST:8080/api/message"
method: POST
content_type: "application/json"
payload: >
{
"boardSlug": "{{ board_slug }}",
"message": "{{ message }}"
}
```

Example service call:

```yaml
action: rest_command.flipoff_send_message
data:
board_slug: bedroom
message: Washer cycle complete
```

If `boardSlug` is omitted, FlipOff sends the message to the current default board.

I’m not ...
