Wordmove command integration

[VesterDe]

This allows wordmove usage via

wocker wordmove COMMAND

I used the same code used for wp-cli and wrote basic instructions.

@mariojankovic Working on Wocker v1.2. Hoping I can release it this month.

I hope everything is going ok with Wocker v1.2. I don't know if this will be included, but if anyone wants to use Wordmove with Wocker it has gotten increasingly complicated with the last few releases. I haven't researched deeply into how to solve it long term.

My minimum viable effort is:

1. vagrant ssh into wocker
2. wocker exec -it _imageName_ bash where imageName is whatever image is running right now.
3. apt-get update, to get apt-get working.
4. apt-get install lftp, because wordmove needs it.

At this point, it used to be enough to apt-get install ruby, but wordmove needs Ruby ^2.4, which isn't the one you get by default. So my solution is

5. curl -L get.rvm.io | bash -s stable, to get rvm (ruby version manager).
6. source /etc/profile.d/rvm.sh, to make it work
7. rvm install 2.4, it should also make it the active version, check via "
8. gem install wordmove, ruby versions below 2.4 fail on some dependency or another here.
9. wordmove init, and you're done.

Well, point Nr. 6 needs to be repeated each time you go into the docker bash.

Good luck.
