Fluctuating MRT

Closes #80

See merge request walberla/walberla!220

This was lost in the migration from boost to std as boost::hash<T> (and thus boost::unordered_map<T,V>) uses hash_value<T> if available and std::hash<T> (and thus std::unordered_map<T,V>) does not.

We do our own availability detection in CMake, so we don't care about the deprecation.

This option is OFF by default.
If turned on cmake will notify if a target cannot be build due to a missing module.

[API] removed rpos from all body constructors

Changes: Bodies that are part of a union now store all attributes relative to its respective coordinate frame. This affects gpos and q (Rotation), which are implicitly relative once a body becomes part of the union. These properties became private and the global Position can be accessed via getGlobalPos() which performs a recursive calcuation of the position of this body in the world frame. This avoids error-prone update procedures, if a Union is tranlated or rotated.
