Byzantium 1.4b file

1.Added Megali Idea focus. 2.Removed Bulgaria and Cyprus Friend focuses 3.Rearranged early claims focuses. 4.Added focus icon. 5.Changed two focus icons. 6.Added two events each for Constantinople and Athens falling and being recaptured. 7.Removed non-aggression pacts. 8.Fixed Three Romes event so it fires again. Note: Spent more time tinkering with the focus icons than adding events. Just not happy with the Megali Idea and Justiniains Dream icons. Think I'm finally satisfied with the non-aligned focus. I want to do more with the political and industrial focuses but just have not settled on anything yet. Have still not written any of the claim to core events or the rename events. Apologies if changing the focuses breaks anyones save game.
