Add more Functionality to Unbind

The default keybinds can be unbound either for a specific mode, or for every mode.
It supports either a list of `keybinds`, or a bool indicating that every keybind
should be unbound:

```
keybinds:
    unbind: true
```
Will unbind every default binding.

```
keybinds:
    unbind: [ Ctrl: 'p']
```
Will unbind every default `^P` binding for each mode.
```
keybinds:
    normal:
        - unbind: true
```
Will unbind every default keybind for the `normal` mode.
```
keybinds:
    normal:
        - unbind: [ Alt: 'n', Ctrl: 'g']
```
Will unbind every default keybind for `n` and `^g` for the `normal` mode.
