Validation in data entry forms

[larshelge]

Add support for running validation rules for data in a data entry form. Add a "Validate" button to the end of the data entry form. Clicking on this button should trigger a validation check against the current data in the form. If any checks fail, a list of validation rule violations should be presented to the user. Failed validations should not stop the user from saving the data.

This check must happen client-side and be available off-line.

Validation rules can be retrieved from /api/validationRules resource.
