Added Game Rule for Dynasty Notifications
Post Scythe Changes to Pregnancy and Mortality Values

Fixing diplomatic range issues....perhaps next I'll look at a couple of the gui issues that are still lingering.

Made it a little more possible for younger folk to become commanders under certain circumstances.

GUI fixes so that Pesky Caliphate icon doesn't show in the HUD unless it's supposed to.

Change of default game rule to expanded historical empires due to historcal empires breaking legends and added e_britannia to that trigger.
