ECWolf 1.4.0 made several changes that make it easier for Linux distros
to create packages for ECWolf [1]. ECWolf now generates its own desktop
shortcut, so we no longer need to use makeDesktopItem. ECWolf now also
will look in the CMAKE_INSTALL_PREFIX/share/ecwolf directory for
ecwolf.pk3, so we no longer need to patch src/version.h or copy
ecwolf.pk3 manually.

This change makes ecwolf’s src slightly simpler. It also makes ecwolf’s
src more future proof. When ECWolf 2.0 is released, the “1.x” in the
maniacsvault.net URL is likely to change, but the Bitbuck repo isn’t
likely to change. Additionally, this change reduces the difference
between ecwolf’s default.nix and lzwolf’s default.nix (LZWolf is a fork
of ECWolf). Finally, this change makes nixpkgs rely on bitbucket.org
instead of maniacsvault.net. bitbucket.org is probably more reliable
than maniacsvault.net.
