Add playerctl v2 backends (#142)

* Add playerctl v2 backends

* Player should be the last arguement as it's optional

* Make v2 backwards compatible with v1

* Make cli v2 backwards compatible as well

* Delete playerctl and rename playerctl_v2 to playerctl

* Add deprecation for global signals

* Update the docs

* Player should be optional

* Fix image downloading failing on some cases

### Usage
To enable: `bling.signal.playerctl.enable()`
To enable: `playerctl = bling.signal.playerctl.lib/cli()`
To disable: `bling.signal.playerctl.disable()`

- `backend`: This is a string containing the name of the backend that will be used to produce the playerctl signals, either `playerctl_cli` or `playertl_lib`. `playerctl_cli` is used by default because it is supported on most if not all systems. That said, if the playerctl package for your distribution supports the `playerctl_lib` backend, it is recommended, because it supports all the configuration options as seen in the table above and uses less system resources. If you are not sure if your package supports the `playerctl_lib` backend you can simply try it and will receive an error message from Awesome upon calling `bling.signal.playerctl.enable()` if it is not supported. See the examples below for how to set configuration options.

- `interval`: This option is a number specifying the update interval for fetching the player position. It is 1 by default.
These options can be set through a call to `bling.signal.playerctl.enable()` or these theme variables:
- `debounce_delay`: This option is a number specifying the debounce timer interval. If a new metadata signal gets emitted before debounce_delay has passed, the last signal will be dropped.
This is to help with some players sending multiple signals. It is `0.35` by default.
These options can be set through a call to `bling.signal.playerctl.lib/cli()` or these theme variables:
