Added url to find nearest squid, added new thread
Added new class `middleware` to deal with deleting inactive squid every
`interval` seconds, this class also maintains the integrity of the
GeoLiteCity database.
Moved static folder to save directory as shoal.py due to pathing issues
with development webpy server.
Added squid favicon!
Added supporting python functions to finding nearest squid in geoip.py
Changed shared resource between threads `shoal` to be a dictionary with
the key being the public ip (can change) of the squid server. Removing
from the dictionary is O(1) time, which was better than my array
implementation which was O(n).
Added some css to html pages to spruce them up a bit.
