EclipseFP optdepends (part 2)

After I completed list of optdepends for EclipseFP just few days ago, the list was extended by new testing framework (HTF) - which is actually recommended one (with GUI support from EclipseFP).

Like last time, I've uploaded built packages into https://s3-eu-west-1.amazonaws.com/archpackages so you can grab them using

```bash
for file in $(curl https://s3-eu-west-1.amazonaws.com/archpackages | tr '<>' "\n" | grep "tar.xz" | grep "eclipsefp-optdepends2" ); do wget https://s3-eu-west-1.amazonaws.com/archpackages/$file; done
```

or any other means to browse/download from Amazon S3.
