CAPI Multiple PaidFor fixes

[emma-imber]

What does this change?

A number of small fixes for the CAPI Multiple PaidFor template:

• Adds target="_top" to the CapiCard link to ensure that articles open up in the full window and not just the ad iframe (see figure 1)
• Adds a margin: 0 to the body so that ads on Firefox display as expected (on Firefox the default margin is not 0, see figure 2)
• Resizes the headers to line up with the lines on the webpage, as the width did not take into account the 40px padding (see figure 3)
• Also set the test.json to an active campaign to help with testing

Figure 1

The link should open in the main window, not the iframe

Figure 2

The ad shouldn't have any extra margin around it (Firefox specific issue)

Figure 3

The right side of the header should line up with the line above it
