Editor comment

[MatusGuy]

The editor comment allows level designers to leave a note for themselves or other level designers collaborating on the same level. Similar to a code comment, it can be used to write to-do lists, fixmes, or notes.

This feature supports info box formatting, like what you'd see in the info block or the text scroller.

Testers: Please test all formatting features in the editor comment (of course), the info block, and the text scroller (via credits, I guess).
Use this as a reference for all formatting features:

supertux/src/supertux/info_box_line.cpp

Lines 67 to 87 in 79c6ee8

	InfoBoxLine::LineType get_linetype_by_format_char(char format_char) {
	switch (format_char)
	{
	case ' ':
	return InfoBoxLine::SMALL;
	case '\t':
	return InfoBoxLine::NORMAL;
	case '-':
	return InfoBoxLine::HEADING;
	case '*':
	return InfoBoxLine::REFERENCE;
	case '#':
	return InfoBoxLine::NORMAL_LEFT;
	case '!':
	return InfoBoxLine::IMAGE;
	default:
	return InfoBoxLine::SMALL;
	//log_warning << "Unknown format_char: '" << format_char << "'" << std::endl;
	}
	}
