Protocol images and bug fixes for invoices and imports

Changes Docker configuration so that protocol images can be served by the minio s3 service instead of requiring an external image server.

But, mostly, fixes several issues in Aquarium:

• invoices now scroll and the page no longer crashes when there are no invoices.
• protocol import now properly handles UTF-8 characters, and allows partial types for an operation input/output.
• includes English language tags in HTML page templates so that Chrome doesn't treat Aquarium like it is in Somali.
• jquery is updated to deal with security issue
