This way we no longer have people confusedly editing mediagoblin.ini
when they meant to edit mediagoblin.example.ini. Hopefully it should be
a lot simpler.
Tries to simplify a lot of the configure code. This is mostly because I
found what I expected the previous configure setup to do wasn't quite
what it was doing.
Also supports a --with-python3 option.
Why do ./configure && make && sudo make install if the second one make
installs, amirite? ;)
Generally I just think install should not be a default make target.
