Map Information tool

A Happy New Year to all of you.

During the past week I have written a 'Map Information' tool:

@dg0yt, @lpechacek: please have a look at it and give me some advice how to proceed (e.g., std::map vs. std::vector and 2 or 3 column layout). To be discussed: 'Map' item offers the same information as the 'Objects' item. Commit

Fonts: In a cross-platform scenario, I would be interested in the substitutions chosen for missing fonts. (But this could be added later.)

I tried and used

auto font_info = QFontInfo(text_symbol->getQFont());
auto font_family_substituted = font_info.family();

However, I'm not sure how to show it: or: or:
