Second half of https://jira.translate5.net/browse/TRANSLATE-4106:

• Add Base class (Map) to detect overlaps with other elements of the Frame. This Class/Map then can be used later on in the table-rendering as well
• Render sequences of paragraphs or list-items as own micro-layouts to the visual to improve the element-growth in case of longer translations.

Already Implemented is the detection of sequences of paragraphs & list-items, even the rendering is implemented but they cannot be rendered without an improved table-rendering as the rather "big" elements will cause overlapping-problems

Can be released only in conjunction with https://jira.translate5.net/browse/TRANSLATE-4107
