As a user I'd like to see how the petition is doing, how many signups are there already, what is the target.

I'd like to add the "progress bar" version of the counter to the form block. I don't think that any petition would want a form without progress bar so let's make it a standard part of the form block (for now).

This ticket is only about the design, I'll open a separate ticket about the backend of the progress bar.

Some considerations:

• we will have three layout versions of the form block so we'll need a progress bar for all versions (though
• most of the progress bars i've seen are on the top area of the form, but usually underneath the title of the petition. see: http://heartoftheamazon.org/
• the counter block has 3 layout versions but i'd only use the "progress bar" version in the form block
