License Jibb under MIT

Montelot chose the MIT licence, as urbit/urbit has (review question 45, A107). LICENSE holds it, and the example app's docket says MIT. The README's new Licence section names the two kinds of files that are others' work under their own MIT licences: vendor/, copied from urbit/urbit, whose licence at the pinned commit is now in vendor/LICENSE-urbit.txt (tools/ship copies only vendor's package folders into desks, so it stays out of them), and the Tlon importer fixtures, whose licence was already in tests/importer/tlon-license.txt.

8585It matches each labelled block to the case whose `source.jibb` is the block's text plus a newline, and lists the blocks no case holds, each with a diff against the closest unmatched case, and the `doc-*` cases no block holds. Pass every tab with Jibb blocks, or the other tabs' cases count as stale. The exit status is 0 when every block has a case and every case a block, 1 when one doesn't, and 2 when the check can't run, for example because no block is labelled `jibb`.

87+## Licence
88+
89+Jibb is under the MIT licence, in [LICENSE](LICENSE). Two kinds of files in it are other people's, under their own MIT licences: the files in `vendor/` are copies from urbit/urbit, whose licence is in [vendor/LICENSE-urbit.txt](vendor/LICENSE-urbit.txt), and the Tlon `/sur` files that `tests/` uses as importer fixtures come from tloncorp/tlon-apps, whose licence is in [tests/importer/tlon-license.txt](tests/importer/tlon-license.txt).

8791## Fake ship

8993`tools/ship` runs the desks on a fake `~zod` at `/root/urbit/zod` (`--pier` or `$JIBB_PIER`). It needs Python 3 and click (`/root/src/tools/pkg/click/click`, or `--click`). The ship runs in the background, logging to `/root/urbit/zod.log`.
