Fix handling of multi-value file fields

Some clients (e.g. Swagger), rather than specifying `file1`, `file2`, etc... will
specify multiple values for `file` when uploading multiple files.
This code change will handle lists of values for individual fields.

Menagerie of job handler improvements

Add range read and other request information to file download documentation

Support <id:xyz> syntax in resolver

Add single file range read feature

Replace RAML with Swagger and removed ABAO tests

Also separated concerns between travis git initialization and pushing docs to the gh-branch.

This includes mention of literal style folding, field ordering, descriptions in JSON schemas.

Coverage report is generated by running integration tests, and
coverage can be checked by running `grunt coverage`.

Lint errors will now break the build.

Also reduces number of lint false positives.
