biojava-modfinder requires external resources that are no longer freely available

All files needed are from phosphosite resource, e.g.:

https://www.phosphosite.org/downloads/Acetylation_site_dataset.gz ,

They give a 403 error code on download (forbidden). The only way to download it now seems to be by going to the website and logging in.

I contacted the phosphosite resource a few weeks ago when I first saw this issue, but they never got back. So I guess their plan is to keep it as a private resource that is not usable for automatic downloads (at least without a login).

Update: it looks like this is some sort of security feature (apparently provided by CloudFlare, at least that's what the error message says).

It would seem that the server detects the user-agent and responds differently depending on what it is. I get a 403 with:

• curl
• wget
• Java URL.openConnection() (the one actually used in BioJava code)

But I get a 200 with:

• Chrome browser
• Firefox browser
• Java jersey client
