This patchset makes the shell capable of lazily resolving and executing sequences of commands, to allow for putting logical sequences in the background. In particular, it enables And/Or/Sequence nodes to be run in the background, and consequently unmarks them as `would_execute`. Doing so also fixes job control to an extent, as jobs are now capable of having 'tails', so sequences can be put in the background while preserving their following sequences.
