Pre 0.B mutations

Some last-minute love for Cephalopods (pre-thresh); likely either post-thresh for Rat or a pre-thresh Horse category will be worked in too.
if the original strings are the same, you need to write `pgettext("foo-bar-male", "%s bites %s!")` and `pgettext("foo-bar-female", "%s bites %s!")`.

The string inside the `_()` is used as key to the translation, the translation system stores one translation (per language) for "%s bites %s!". In other words "%s bites %s!" is translated to the same string in both branches.

`pgettext` (also used when calling `u.add_memorial_log) adds another string (the context) to the translation. `pgettext("a", "text")` and `pgettext("b", "text")` can be translated to different strings.

Or, as you proposed, making the text gender specific in its original form would also work (-:
