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.

Please keep in mind that this is just the first version of the Map Information.
Any proposal for additional features is welcome.

I also added an overview about the fonts and their usage.
The 'Objects' section now shows for every symbol which colors are used by it.
The 'Colors' section shows all colors and by which symbol every color is used:

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:
