The new version fixes parse transforms over OTP incompatibility that
would crash entire compile runs before.

cth_readable 1.2.0 uses cf 0.2.1 to output colors, which makes it
support dumb terminals without issue.

This fixes a typo that could cause failure in some test runs.

- eunit assert look better
- lager logs to the html logs

This uses cth_readable to:
- silence error_logger output to the shell unless a test fails
- silence ct:pal output to the shell unless a test fails

I have currently not baked in any way to disable this behaviour, but I
figured if it is required, there is time to do it before the final
3.0.0 release.

fix #790

- Crashes in providers lib when no providers in a namespace are bare
- Making sure bareness matches semantics; i.e. a bare provider is
  visible, a non-bare provider is hidden.
