The difference for builds from scratch is negligible, but for rebuilds (i.e., for us hackers & the CI here in front) it should bring a speed improvement.
Automatic fallback to Make when Ninja is not available, or override with `USE_MAKE=1`.
You can (theoretically) choose your own generator with a sensible combination of `CMAKE_FLAGS` and `CMAKE_MAKE_PROGRAM`.
I also added `MAKE_FLAGS` and `NINJA_FLAGS`. That way you can easily pass `MAKE_FLAGS=-n` or `NINJA_FLAGS=-n` for a dry run, for example.
To switch you might have to run something like `make dist-clean USE_MAKE=1`.

* junit test results; unfortunately this seems to conflict with the verbose out
* fix deps cache: two files can change independently
* verbose print obsoleted by gtest in upsream busted
The debug output from Coveralls was rubbish. `"Build processing error"`
Besides some basics like checking if we were actually sending
valid JSON that gives us absolutely nothing to work with.
* Enable parallelism in .circleci/config.yml
* Add BUSTED_SPEC_FILE to Makefile testfront
* Use it in .ci/test.sh with xargs for test parallelization
NB This is the dumb method of improving test time.
Ideally we want a workflow fan-in/fan-out approach.
* shellcheck 0.4.5 fix `LC_ALL: en_US.UTF8` (can be removed for shellcheck 0.4.6)
* hush updated luacheck on `reader.lua`; we're not assigning any variables but `= nil` is redundant
