BGE Fix for: [#22142] Armature deformation does not work in Game Engine. + parent type to modifiers doversion(). Patch by Xavier Thomas (xat)

This fix the problem of not being able to play animations created with Blender 2.5 in BGE. Patch reviewed by Benoit

Added also other parent to modifier conversions as requested by Joshua (aligorith). I didn't bump subversion here, but the patch should work still. If not I'm increasing subversion sooner anyways (tomorrow or by the middle of the week I hope).

I was waiting to commit this one together with the Logic Editor datablock patch (converting material_name DNA properties to struct Material *). However my patch is getting too big and it's better if it's alone (easier to analyze later, eventual fixes, ...)

Mitchell, this commit adds a function that can help hardware skinning - HasArmatureDeformer()
