Correct configuration for i18n-js w/asset pipeline

`I18n::JS::Middleware` is only necessary if we're not using the Rails
asset pipeline.

See https://github.com/fnando/i18n-js#rails-app-with-asset-pipeline

If we migrate away from the asset pipeline, this commit should be
reverted.

Fix board pagination

TablePagination directive: Add support for a updateResults callback again,
which apparently was removed in favor of emitting WorkPackage-specific events.

Kept all the events and calling the callback on page and per-page change now.
Board pagination: Pass per_page parameter to API

Before, per_page was ineffective.
Angular pagination: Add default per_page value to options

I guess it doesn't make much sense having a value as default here
that a user later can't select again.

API v2: Change boolean value to use true/false

While this is not the OpenProject API, we use true/false for other APIs and for other parameters in the application, like `layout=false`. true/false also seems more intuitive.
