i18n (internationalization) needed #26
Description
The plugin currently uses the text-domain "gf-zero-spam", but for correct loading of the language pack, the text-domain should be equal to the assigned plugin slug, i.e. "gravity-forms-zero-spam".
If we at the same time add "Requires at least" to the PHP file, and raise the value from 3.0.1 to 4.6, then WordPress core should automatically load translations.
