Camera moves to face slide even if slide was moved

The camera_poses plugin scripts the camera movement to specific poses. It would be interesting to make the camera face a certain slide instead. This way. the user is able to edit the final world, move slides around and the camera plugin will adapt accordingly.

It might be interesting to keep the current behaviour as well, so a combination of facing slides and looking at other places can be done.

As of ROSCon 2016:

• Using igniton::math::Matrix4d::LookAt to always look at slide, even if it was moved. The up direction is always Z though.
• Combination of lookat + other keyframes is still hardcoded
