Reasoning being:
* The result_set and other APIs are nicer to use.
* We use mariadb on our server rather than mysql, so this would minimize the chance of any incompatibilities.
* The mysql C++ connector 1.1 isn't compatible with with c++17 (https://stackoverflow.com/q/47284705).
Rather than having everything in the MOTD, this adds a separate button that will popup a window which will have most of this information in two tabs:
* General server information, such as a link to the CoC.
* Announcements, such as tournaments and new versions being released.
The information on this new window will be stored in the new `server_config` database table.
The MOTD will then just be a short greeting instead of the several lines that are shown currently.
Additionally, now the motd will only be displayed in the lobby chat the first time the user logs on.
Loonycyborg already uses these tools with Python 3.
The python launcher tool for Windows has magic handling for some shebang lines,
however `#!/bin/env python` isn't recognised without the `/usr`. Had the `/usr`
been included with the old code then these scripts would likely have been run
with Python 2.

before the 'ignore unused addons' commit, the engine reordered [terrain_graphics] to make mainline [terrain_graphics] appear after umc [terrain_graphics] tags, this commit restores this behavior (instead of using [terrain_graphics]precendence= in mainline which would be an alternative fix). If we ever use game_config_view for anything else than the game_config we can also make this an optional "bool put_first_source_last" parameter.
This comment will be added at the start of any .cfg file written by the
scenario editor. Given that the only target audience is authors using text
editors, it's not translatable and uses plain ascii characters.
Eases the assertion concerning nonzero window dimensions in
gui/widgets/window.cpp; it turns out that some windows do request zero
dimension, and it doesn't hurt anything for them to.
Fixes#4960.
This reverts 24af20cf83, which made it available in debug mode only, as there remain more differences to the new default AI than initially envisioned. This takes care of Issue #4997.
