addon-metadata.xml: add meta section (non-leaf node) and file-type node

Browse source 
Move the format-version node inside /meta. It's not compatible of
course, but since the stuff this is breaking is only 2 or 3 days old,
let's go for it for nicer code and file format.

Sorry if you had already written an addon-metadata.xml file of your
own. In this case, just replace:

  <format-version type="int">1</format-version>

with:

  <meta>
    <file-type type="string">FlightGear add-on metadata</file-type>
    <format-version type="int">1</format-version>
  </meta>
