Data binding for HTML components

[syncro]

In some cases usage of flowui components can be not enough to fit developer's requirements and java-side data assignments to achieve simple display purposes may feel too verbose. So there should be a way to easily render context data into custom ui layout, e.g. to show label with localized field title or span with database entity field value.

Possible solutions:

1. Add property attribute support for all or most-used and suitable html components, e.g. for container-like ones: span, div, label, headings, lists etc.

2. Implement new component for data binded output or add data-binding to html/div componets only
