Subject: [PATCH] Add copy and paste aliases to clipboard commands

Interact with the clipboard through the `copy` and `paste` aliases.

`copy` is defined when:

1. An `ssh` connection is detected, using OSC-52.
2. macOS is detected, using `pbcopy`.
3. `xsel` is detected.

`paste` is define when:

1. macOS is detected, using `pbpaste`.
2. `xsel` is detected.
