by Scyther: Fixed call to undefined function in countries_api_numcode_get_country(). Fixed Coder warning for SQL query. Renamed _countries_api_iso_get_country() to _countries_api_get_country() but keept the original function to support other module that uses it. Added constants for all the formats.

Issue #1258532 by KMC81:  is defined but never used in countries_api_help(). Updated function documentation.

by Scyther: Fixed some minor indenting warnings from Coder module and fixed TODO for description for db table in countries_api.install.
