Rewrite the HTTP handling

- adding http_GET/POST/PUT/DELETE() functions, which dispatch to
   http_request(), and use them everywhere
 - removing othermethods.py 
 - keeping urlopen(), in case it is used from externally, but have it print out
   a "depracated" message
 - finally, implementing a global HTTP debug mode
