Indentation in application/metadata.js needs fixing up

• [ should be on its own line, indented 4 spaces.
• Subsequent objects etc. should be indented in multiples of 4 spaces.

Addressed in PR #27 I fixed the metadata generator and then used it to generate the last version of the metadata.js file.

This should be fixed with PR #27
