Stop PPCoin addresses overflowing the panel

This was a problem on the Project Sponsors panel as demonstrated at http://peer4commit.com/projects/1. This change makes the entire block gain a scroll bar if necessary, so that the entire value is still accessible, but it is not in the way, overflowing onto the top of the main content.

This was mainly an issue for a viewport width in the range 992–1199px, though with a significant percentage of wider characters (e.g. lots of W's, not many i's) it could still appear outside that range.

Fix- generate proper HTML
    Previously html attributes is put inside the "html" option which was generating wrong html
      <form html="{:role= \"form\";, :class=\"form-inline\"}" accept-charset="UTF-8" action="/projects" method="post">
      </form>
   Now I removed the html options and passed html attributes directly:
      <form accept-charset="UTF-8" action="/projects" class="form-inline" method="post" role="form">
      </form>

Make the peer4commit tags more readable

I personally find the peer4commit and the tip4commit tags very small and hard to read. It is hard for me to test but I think this code will help out.
