Remove default country param

The country URL param ('gl') is no longer set to 'US' by default, and is
omitted from the search entirely unless explicitly set by the user. This
change was made in an attempt to cut back on the number of captchas
experienced by certain users self-hosting who experienced a decreased
amount of captchas when this configuration setting was removed.

Fixes #558
