EmmaFormatter writes wrong values for aggregated values

[leifbladt]

The line coverage in percent isn't correct for aggregated values (packages and all classes), though the count of affected lines is.







<srcfile name="admin_controller.rb">
  <coverage type="class, %" value="0%   (0/0)"/>
  <coverage type="method, %" value="0%   (0/0)"/>
  <coverage type="block, %" value="0%   (0/0)"/>
  <coverage type="line, %" value="100%   (3/3)"/>
</srcfile></code>

With a little research I found out, that the missing values are currently not inserted in the XML template, as these information seem not to exist right now.

I started to add the executed_percent to the GlobalReport class (leifbladt/cover_me@c6f9a7629841bab2f91d). Do you think, this is the right approach?
