Implement multi position object in .animated file

[adfriz]

Now we can write multiple position in single [object] section

before

[Object]
states= chair.b3d
position= 0,0,0

[Object]
states= chair.b3d
position= 0,0,2

[Object]
states= chair.b3d
position= 0,0,3

and so on...

now

[Object]
states= chair.b3d
position= 0,0,0
position= 0,5,0
position= 5,0,0
position= 0,0,-5

although it works on object viewer, its obviously need more test and make sure not break other code.

some practical use is player making passenger car that have 2 + 2 row seats with multiple column and want tweak each position a bit. but really any object player wants, like maybe player wants to scatter trees across area and want exact position for each tree.
