Grzegorz Kowal 0494df3285 Add CONSERVATIVE flag to the build system.
- CONSERVATIVE flag determines if the scheme must be fully
   conservative; this works only when adaptive mesh is used; in such a
   case instead of update variables at each block, we first calculate
   high order integration of fluxes, then we synchronize them between
   blocks at different levels, and finally we perform one-step update
   for each block using updated fluxes; this might be also a first step
   to implement Galerkin methods;
