sender_info needs valid values

[laroque]

Ideally these can be generated dynamically, if that's not easy/possible, there need to be valid values stored somewhere and used throughout.

In the h2d version of firefly I had taken care of a few of the fields. Perhaps that's useful here.

• hostname: dynamicall filled in with the built-in php function gethostname()
• package: hardcoded as firefly
• exe: hardcoded as none. Perhaps instead you could use the page name that generated the request.

done thus far:

• username: from the session cookie if present, otherwise <unknown> (firefly should not allow access to pages if you aren't logged in, demo page from dripline-web still behaves reasonably)
• exe: will be the webpage used to send the request
• package: always dripline-web
• hostname: from gethostname()

I don't have a good solution for commit and version other than manually storing/updating them from a file (which is gross and error prone). The container doesn't have git installed so git describe isn't an option.
