Padreug b2b2c109a4 Clean up awkward "the Libra" phrasing left over from rename 
Replaces entity-sense references to "the Libra" with "the
organization"/"the collective" where Libra was being used as a
stand-in for the original "Castle" entity, and drops the redundant
"(like cooperatives)" parenthetical in DOCUMENTATION.md. Also swaps
the 🏰 emoji in the import helper for ⚖️.

Closes #12

  • Generate Lightning invoices for settlements
