The widget uses 'wget' to grab the information. The Lua socket library
would be nicer, of course, but let's not introduce external libraries
at this point. Wget will write to stdout with a timeout of 5s. This
has the potential to block everything else in case of problems... But
let's not introduce temporary files at this point. Besides having to
handle files, operations while running on battery power are to be
avoided.
