[fixed]Orge .skeleton animation loading bug and fix

[sobieh]

I have read hybrid post saying Ogre animations are not supported due to some wrong data when reading keyframes so here we go:
First of all the Keyframe loader reads keyframe data in wrong order:

COgreMeshFileLoader::loadSkeleton


// Wrong order
readFloat(file, data, &keyframe.Time);
keyframe.Time+=animationTotal;
readVector(file, data, keyframe.Position);
readQuaternion(file, data, keyframe.Orientation);

// Correct order
readFloat(file, data, &keyframe.Time);
keyframe.Time+=animationTotal;
readQuaternion(file, data, keyframe.Orientation);
readVector(file, data, keyframe.Position);

Second bug is a wrong quaternion rotation transformation:

COgreMeshFileLoader::composeObject

// WRONG
rotkey->rotation = frame.Orientation + core::quaternion(keyjoint->LocalMatrix);

// CORRECT
rotkey->rotation = core::quaternion(keyjoint->LocalMatrix) * frame.Orientation;

With these fixes i can load .mesh and .skeleton files with no problems.

PS:
It would be also usefull to allow loading of .skeleton files separately.

Very nice catch. Already commited to 1.7 branch I've noticed some problems with the default models from Ogre SDK, also some other models from my own repository have many missing weights (don't know which serialization format they're from). So not yet full support for this format, but might be working already
