Release v0.3.2

Since version 0.3.1, these changes have been made:

• Upload File Field. There is now an upload file field type. This is useful, for example, if you are building a job application form (see below example screenshot).
• ID-Based Validations. Validations are now managed by validation ID rather than by validation alias. This helps to ensure the validations work even when no alias is specified.
• Button/Label Markup Changes. Added a CSS class to labels and restructured the button markup. Useful for adding custom styles (e.g., if you want to hide labels or if you want to underline text with a border rather than text decoration).
