Fixed mbtools not to use polyBlock* anymore.
Bugfix fuer LB print function
Reformatted the LB tcl interface, so that it is much cleaner, and also got rid of all the ARGx_IS_S commands in favor of ARG_S_IS_EXACT, since the amount of problems these give with having similar names and opening characters is not worth the added benefit of using shorthand notations.
Removed left over printf statement.
copy_particle now copies in order of identities
copy_particles now returns the mapping
Merge branch 'master' into Merged_EK_newest

Keep this branch up to date with the master.
Changed the OutArray statements in the LB vtk output to the name of the quantities, to ease the idenfitication in paraview.
