Title: Install php5-gd dependency for selfoss.

When trying to refresh some selfoss rss feeds, I get an error related to processing images:

```
Internal Server Error
Fatal error: Call to undefined function imagecreatefromstring()
```

Installing the php5-gd dependency fixes this (on Ubuntu, at least). I went ahead and made the selfoss php dependencies explicit, too.
