Build-tested all consumers on amd64: no fallout; ok pascal@ (MAINTAINER)
Needs a backport of commit 4f06738 because btSoftBodyHelpers.h is
currently broken: it tries to include code that's available only in
examples/*. Spotted while trying to build games/godot.
while here also:
- update HOMEPAGE (the current one is just a redirect)
- enable the tests (which are all passing!)
