No sorted pair over mpi

Fix to #256. Do not use sorted pairs when the pair task is crossing over two MPI nodes.

Added the missing SSE function in vector.h. Compiles but accuracy is not identical to AVX when running test27.

Update the task plot scripts to include new tasks and subtasks.

Also fixes an issue where gaps between successive tasks of the same type
were not seen as these were joined (for plotting efficiency I guess).
A gap is now seen.

Also change the colour handling so that the task/subtask types are
easier to differentiate.

Fixes issue #260.

Fix compilation error when compiling without affinity turned on.

Does this seem like a reasonable fix to #261, @pdraper @matthieu?

MPI send/recv fixes for inactive cells

This is open so that we have a live diff of the changes to solve the MPI crisis. Also helpful to keep track of the changes.

Contains all of @nnrw56 @pdraper @matthieu's changes to this stage.

Also see #256.

See merge request !303

Call runner_doself1_density_vec in DOSUB_SELF1 if vectorisation is enabled.

Changed all `WITH_VECTORIZATION` macros to WITH_OLD_VECTORIZATION in `runner_doiact.h` so Pedro's old vectorised functions are not called.
