Windows build docs need a minor update (missing autotools package)

[MFG38]

The documentation at https://www.chocolate-doom.org/wiki/index.php/Building_Chocolate_Doom_on_Windows has a very minor flaw in that it makes no mention of the autotools package, which the autorun.sh script needs in order to run. I banged my head against the wall for the better part of an hour wondering why the script was producing the following errors:
./autogen.sh: line 3: autoreconf: command not found
./autogen.sh: line 4: ./configure: No such file or directory

...looking through past issues related to said script for answers until I somehow stumbled upon one where autotools was mentioned. Installed that and ran the script and voila - it ran without errors. I would have edited the wiki page myself and added autotools to the list of dependencies, but apparently pages on the wiki can only be edited by registered users - which I understand in a way, but that's another discussion entirely.

May this issue also act as a reference for anyone else who may run into the issues I did.

I ran into the same problem. Running pacman -S autotools before ./autogen.sh --host=i686-w64-mingw32 fixed the issue.
