Improve the HTTP plugin by allowing configuring a proxy and friendly name per URL.

Browse source 
Note that the configuration file syntax has changed. You need one "url"
variable per URL now, numbered starting with 1, e.g. url1, url2, url3.
Each one can be configured by suffixing its variable, e.g. url1_proxy,
url2_proxy, etc.
