SGS Overlord : update 1

Some corrections and additions to the map (names / positions of certain villages, Dives, Mézidon…)

Minor changes to initial positioning in the grand campaign (Panzer-Lehr Division, Grenadier-Regiment 915…)

Minor unit corrections (2nd British Army Victory Points in particular)

AI tweaks to optimize behavior (notably the American army in the Cherbourg scenario)

A few corrections and updates to the Overlord manual for greater clarity, including unit repair costs in replacement points.
1>1: Allied fighter-bombers and German infantry
2>1 : Specialized, armored and mechanized units on both sides; Allied medium bombers
3>1 : German fighters (overwhelming inferiority and lack of pilots)

Thanks for your support, more will follow later.
