* Replaced use of a config with data structs.
* Moved [about] sorting to the parsing stage instead of handling it in the End Credits dialog.
This improves on my refactoring work here from 2016 (476027f239).
Turns out I mistook @celticminstrel's opinion that we should use include guards over pragma (737916e).
Since all major compilers support `#pragma once`, there's no reason not to use it.
For future mergability reasons, this excludes src/spirit_po and src/xBRZ. It also excludes src/boost-patched.
This removes the ugly string markup and makes the dialog parse the config directly.
This also temporarily disables the display of credits in the help browser.
Multi-line section headers such as those generated by campaigns with
multi-line titles result in slight scrolling glitches because the
scrolling code assumes every entry in the text vector to comprise a
single line.
We don't want to split those headers for the help screen because the
current approach results in nicely formatted headers for the
Contributors page there, so a hacky compromise for now should be to only
split multiline headers for the scrolling credits.
An alternative would have been to make the text vector a linked list so
about::show_about could deal with this issue directly, but that seems
rather wasteful.
* Wesnoth is distributed under the terms of the GPL version 2, made
that more explicit
* updated the copyright range to 2007
* updated Dave's email adress
- changed include paths to be relative to source root
- removed some unnecessary includes
- added some includes of global.hpp to editor files to prevent useless vc++ compiler warnings
- Extended vc++ project files
- fixed the bug of having to press escape two times in a continuous replay to get back to the titlescreen
