Change horribly confusing names of unit cell comparison functions

cells_are_similar -> compare_cell_parameters_and_orientation
compare_cells -> compare_reindexed_cell_parameters_and_orientation
cell_tool.c:cells_the_same -> cellutils.c:compare_cell_parameters

All comparisons now done in real space, checking that centering is the
same, and without uncentering anything.
