Updated +SAPBR: parsing
HTTP api modified to match specifications.

Moved functions to own global http array.
Functions now return array described in api.
Example array:
 response = { .is_success=true, .status=200, content="<html><body>..." }
Example usage:
response = http.get(URL)
if response.is_success then
	print (response.content)
end
