explicit proxy setting for curl-loader-0.47

[<Fra...@ma...>]

Dear Curl-Loader maintainers,

I needed a way to switch off or explicitly set the curl proxy string for 
curl-loader, without touching the environment or .curlrc.
I couldn't find a hint in the docs or FAQ, so I implemented the "-x" 
option from curl in a quick and dirty way to curl-loader.
Now I am able to do:

./curl-loader -x "" -f ssl-loadtest

Where '-x ""' unsets the proxy. It might be of interest for others and I 
believe it is worth implementing, so I attach the diffs. 

I couldn't find quick enough the size for the proxy string, I simply set 
it to char[255] but it might be worth to look up or use the definition 
from the curl sources.
I am also not sure if I placed the curl_easy_setopt (handle, 
CURLOPT_PROXY, config_proxy); call optimal in loader.c, But it works fine 
for me at the moment.

Cheers,
Frank

Thanks, looks good.

I would keep the buffer 1024.

Could you add explanations of the option to documentation, like README, man
page
and send to me a unified diff from diff -Naru ?
Thanks and your patch is appreciated.

Sincerely,
Robert
