Not pretty, but it fixes out-of-the-box verbosity issues (see GH #881).

This reverts commit 196777ea.

This reverts commit 082c526d, reversing
changes made to 242a29f8.

Geocoder::Lookup "cache" method now public; Geocoder.cache method calls cache method instead of configuration key.

Cache is now lookup-specific.

Also move some lookup-related methods to Geocoder::Lookup module.

This is in preparation for adding Maxmind as an IP lookup.

This requires a parameter to be accepted by the block passed to
Geocoder.configure, which means you don't need to remember that the
method is called "config"--you can call it whatever you want.
This behavior seems more standard for configuration blocks.

Altered the Geocoder#ip_address? method to recognize IP addresses prefixed with ::ffff: as is common with webservers binding to ipv6 sockets

Specify path to VERSION file relative to lib/geocoder.rb.

Figures out whether query is an IP address so you don't have to.
