FreshRSS proper support on rss widget

[ralphocdol]

Example FreshRSS User Query

- type: rss
  title: FreshRSS Test
  feeds:
    - url: https://rss.home.local/api/query.php?user=user&f=atom&t=token&sort=date&order=DESC

The FOSS/Linux is from the Category Title in FreshRSS and the source link is the FreshRSS url

but with this added property

  feeds:
    - url: https://rss.home.local/api/query.php?user=user&f=atom&t=token&sort=date&order=DESC
      type: freshrss

the source will now be the Source's host and so is the link
