FormLayout class

Scrollable layout with fixed content on the bottom.

This is designed for long screens (usually forms with multiple fields - hence FormLayout) with some always-visible, fixed content on the bottom (usually a submit button). The content and bottom widgets are separated with a semi-transparent fade-bar, so it looks like bottom is laid out "above" the content. When content scrolls to the end, fade-bar disappears so that last part of it is fully visible.
