coinspot.py httplib Python 3 Deprecated

[beerbotboffin]

In coinspot.py httplib has been deprecated in Python 3.

Recommend changing from:
import hmac
import hashlib
import httplib
import json
import yaml
import os
import sys
import logging
from time import time, strftime

to:
import hmac
import hashlib
try:
import httplib
except:
import http.client
import json
import yaml
import os
import sys
import logging
from time import time, strftime

Tested working in 3.6.2

The plan was to migrate to requests library...
