Don't clean terminal on each redraw but...

[Lynesth]

redraw directly on existing output !

It's different from my last PR but it correctly removes flickering (at least for me, others will have to test) so everything seems very smooth.

It uses \033[1E which means "move the cursor to the beginning of the next line" and \033[J which means "Clear everything from the cursor to the end of the terminal".
I guess those two could be made into UnixTerminal functions.

Edit: Last change removed the use of \033[1E to put back new lines.

@Lynesth this works really well, the test fixtures need to be updated and I think the new escape code should be added into the terminal package.

This looks fine to me - I can have a look at the tests later, they are pretty hard to modify - I usually just xdebug in to the assertions and copy the output from there to preserve the escape codes. @Lynesth let me know and I can take over the test fixes for this and maybe you want to send a PR to php-school/terminal with these escape codes in the UnixTerminal ?
