tests: use curl instead of wget
curl is supplied by default on macOS 10.12, but wget isn't. As curl is easy
to install on other OSes, just switch the tests over.
For Windows systems, you can obtain cURL from
https://curl.haxx.se/download.html - for other systems, please use your
native package manager.
This undoes 4e7da688a066 and 3ffa12edc05a, as they don't make things much
simpler on Windows (you have to install extra packages either way round),
but they do make things harder on macOS (as curl is supplied by default,
whereas wget isn't).

Good practice for (early) users of evolve
-----------------------------------------
Avoid unstability
-----------------
The less unstability you have the less you need to resolve.
Evolve is not yet able to detect and solve every situation. And your mind is
not ready neither.
Branch as much as possible
--------------------------
This is not MQ; you are not constrained to linear history.
Making a branch per independent branch will help you avoid unstability
and conflict.
Rewrite your changes only
-------------------------
There is no descent conflict detection and handling right now.
Rewriting other people's changesets guarantees that you will get
conflicts. Communicate with your fellow developers before trying to
touch other people's work (which is a good practice in any case).
Using multiple branches will help you to achieve this goal.
Prefer pushing unstability to touching other people changesets
--------------------------------------------------------------
If you have children changesets from other people that you don't really care
about, prefer not altering them to risking a conflict by stabilizing them.
Do not get too confident
------------------------
This is an experimental extension and a complex concept. This is beautiful,
powerful and robust on paper, but the tool and your mind may not be prepared for
all situations yet.
