Tracking: Decouple refine settings

Historically the refine options had a hardcoded list of possibilities.
This was caused by an old bundle adjustment code which did not support
all possible combinations.

Now the bundle adjuster is based on Ceres solver, allowing to refine
anything in any combination.
