Added console-lines output mode which prints each test on a separate line

[smuuf]

Usage example:

$ ./src/tester -C -o console-lines tests/

This is handy for environments with "non-standard" (buffered, I guess?) handling of standard output, for example Github Actions (where a progress of tests cannot be seen until until end-of-line appears, which in standard console mode happens only when all tests finish) or Docker Compose logging output (where in standard console mode each finished test's dot is printed alone on separate line).

Or the console-lines mode can be handy just to see a more detailed progress of tests in all environments, because it outputs something like this:

Passing tests	Failing tests	Usage	Also supports "cider mode"

Also, "cider mode" now shows a lemon emoji for skipped tests.

• new feature
• BC break? no
• doc PR: Added docs for new "console-lines" output mode docs#1027

I like that!

I'd probably just use a slightly different name, like -o verbose?

[smuuf]

I'd think verbose could mean different things for different output modes, so maybe usurping the word verbose for something related just to the console output might not be the best thing to do, future-wise, but other than that I have no strong opinion on that 😄

So if you'd prefer verbose, I can make it be called verbose.

Updated: Renamed to verbose + updated the relevant PR to docs.

I was just throwing that out there, I'm sure someone can think of something better.

Imho 'console-lines' was better. Or just 'lines'?

[smuuf]

I think the word console, as the output is still meant for console/terminal, should be contained in the mode's name.

So for now I changed it back to console-lines. If anyone has some other suggestion, feel free to propose it.

What do you mean, @milo?
