initial commit
add license
update readme in the code
split importing of old goo.gl json into its own file
generalize json get code to handle month etc. not just allTime
make the downloader function into a class so we can query it later for monthly data too
add logic to fill in missing db data from a month ago

this uses the fact that goo.gl has allTime data and data from the last month,
so allTime-month gives (roughly) the state a month ago. this is used to
automatically fill in month-old gaps in the db (if there are any).
update url list
don't fill in monthly data by default. add a -f option to write the fill-in data to the db
use slightly more sane argument parsing for the various download and display modes
update urls
show hit count for each url during download
put all the configurables into a config file that is loaded as a module
add an example config file
add a relatively complete country code lookup file
prompt the user to add unknown countries to the country code lookup file
fix finding the config file in cwd when running the script from elsewhere
fixup inital run with no database present
add usage and -h|--help display
add a blank line after download prints to separate them from the stats summary
