Update to Marching Eagles Waterloo & Marengo

[Titus]

A number of improvements have been made, the most notable of which are -

1 - New Rule - Medium & Heavy Artillery are not permitted to move into the same area as enemy units. Normal tactic is to bombard from a distance.
Light Artillery (typically supporting infantry formations) and Horse Artillery can move into the same area and fire at close range
2 - New Rule - to more accurately reflect Napoleonic Warfare - Units can not move from one area containing enemy units directly to another area containing enemy units. Units now have to move to a non-contested area, usually the rear, before moving round to strike another enemy group. Armies can now prevent a penetration of the Front Line by placing a second line of defense immediately to the rear of the Front Line
3 - Play by E-Mail mode, replay movement when 3 units are in the same area and unit 2 moves out. Unit 3 is required to move into unit 2 position but this does not happen. This results in a loss of focus on the unit - Unit Information Box does not appear. Fault corrected.
4 - Routed unit can not recover cohesion if enemy units in the same area at the end of a game turn
5 - Retreating and routing units are permitted to move into areas containing enemy units
