This reverts commit 97b6bb94.

Move away from generating a `geocoder.rb` initializer with old school ruby hash syntax in favor of the new/current style.

Fixes GH #907.

safe_location and location should not rely on the same variable,
otherwise calling one before the other will yield unexpected results
and could even cause a security risk if location is called before
safe_location

See GH #832.

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

This reverts the parts of commit 350567f5
that are outside of the README and should not have been included.

avoid overriding `use_ssl?` or `protocol` directly
