[New Feature] Restoring the Ice terrain feature of Tiberian Sun

[SMxReaver]

Description:

This feature request is for restoring the logic or recreating the logic involved with Tiberian Sun's Ice feature. This was a special type of passable ground that would be found on snow maps. As time passed on, the ice would slowly expand to fill the watery areas. Units could move upon ice, but heavier units could damage or even immediately sink straight through if too heavy. Restoring this logic and allowing it to be used in any theater (it was only seen on TibSun's snow theater) would allow for more map-based gameplay options for modders to develop.

Possible Implementation:

In Tiberian Sun, ice had a few controls located throughout the rules.ini that allowed for some control over how the ice worked/looked/sound. Restoring these controls or any special logic associated with them would

[General]
IceCrackingWeight=2.0 ; objects weighing more than this will crack ice
IceBreakingWeight=4.0 ; objects weighing more than this well break through ice

[AudioVisual]
IceGrowthRate=1.5
IceSolidifyFrameTime=1000 ; how many frames between when ice is cracked and when it gets solidified
IceCrackSounds=ICECRAK1,ICECRAK2,ICECRAK3

There already exists an [Ice] TerrainType that has valid uses in Red Alert 2 / Yuri's Revenge as a free terrain type for mods to customize.
