[luci] luci.http.header don't works

[Bryan Mayland]

The problem is that you're just running a CGI script, not a LuCI 
response handler so you can't use luci http (because there's no context, 
LuCI isn't even involved).  To make a CGI page spit out the right 
content type:

#!/usr/bin/lua

print("Content-Type: text/html")
print("")  ' header needs to be separated from content by a blank line
print("<b>I am html content</b>")
