0 A.D. currently uses the term "Italiote" [sic]. It's best to use precise language:
* **Italic** refers to a branch of Indo-European and the peoples that speak it (cf. Celtic).
* **Italian** refers to the modern language, descendant from Latin, the people that speak it, and their country (cf. Romanian).
* **Italiot** (from Ἰταλιώτης) refers to Greeks living in Italy (cf. Cypriot).
From the context it's clear what 0 A.D. actually means (Samnites etc.) is //Italic//. This patch therefore corrects the templates and art file names.
The icons (cf. D2551) and tooltips (cf. D2578) of the other embassies are also included for consistency.
NB: I did not adjust the eight `simulation/data/technologies/carthaginians/*.json` files, since those are not actually used and ought to be deleted (D1775).
