[0.90] [Suggestion] Tactical combat - combat speed overpowered

I'm sure I will have more feedback later but after a few battles one thing really jumped out at me.

Combat speed is too powerful.  My sovereign on a horse can attack 3 times or attack and then retreat.  She can also cast 3 spells in a single turn.  This is way too powerful and will end up making things unfun once someone gets a strong unit you are unprepared for.  Really need to decouple movement speed and number of attacks.
