Improved Vehicle disembarking

[MiC17]

Both the disembark module and Zeus' own 'G'-key have the unsightly problem, that, when used, they throw out the selected units all at once in a big heap (looks ugly, doesn't give players the time to react to the threat and makes a giant floating target made of bodies).

For the module to have an edge over standard functionality I suggest looping the script unit by unit so you have them get out one by one in a semi-orderly fashion.

If things need to move fast the 'G'-key is still going to be the method of choice, but in the players' sight the module certainly becomes a viable option.
