* Avoid using `undefined` array when column formatters not specified

This led to `TypeError: Cannot read property "forEach" from undefined`
errors when no formatters were specified.

* Improve logging of unexpected errors during format compilation

* Log unsupported formatting operators and return a dummy operator fn

* Linting fixes

* Manually ES5-ify code that is to be executed by the Nashorn engine

Nashorn in JDK 8 only supports ES5.1.

* Update Rebuilt shared JS from `yarn build-shared`

* Move formatting foctory fns into an operator-indexed object

* Linter appeasement

* Test that all defined operators are supported in table formatting

* Flow annotations

* Return `null` in stead of `undefined`

Formatting/style changes snuck in.

* `yarn build-shared`

* Use operators from table formatting and not column filters
