Subject: Move from OpenWRT wget to curl
X-Git-Url: https://git.sven.stormbind.net/?a=commitdiff_plain;h=8d0198c269d90ea3c1a7f60225aabb7577b7b194;p=sven%2Fscripts.git

Move from OpenWRT wget to curl

The OpenWRT wget implementation aka uci-fetch did not play along
well with the way the meteocontrol weblog HTTP server closes its
connection. To simplify it all just use curl, we need it anyway here.

Also fix up some spaces superflous port definition in the URL.
