Simple HTTP support

[Adam Ruppe]

I've made a very simple curl wrapper:

http://arsdnet.net/dcode/curl.d

It is meant to provide trivial get and post support:

string response = curl("http://mywebsite.com"); // contains the response

curl("http://mywebsite.com", "var=something&v2=moe"); // do a POST


There's functions in my module to do cookies and other things too,
but those functions are kinda ugly. (I just whipped them together to
work without worrying about beauty.)
