* The DM transfer function is now deconvolved with the cell assignment
function in order to restore power near the Nyquist wavenumber.
* Added an option to change the random number sample cube size
[random]/cubesize. This should be set >128 to generate un-
correlated numbers. True fix pending.
* Removed some unused code
* Increased Buffer size for Gadget-2 output plug-in
Fixed a bug with top grid kernel normalization, this reduces errors a bit.
A non-cubic grid is now extended to a cubic grid in the density calculation. This should reduce artefacts due to TF truncation.
Added a new (undocumented and internal) parameter that forces grid centering on the specified refinement region also in unigrid mode. This should in the future also obey that the shift comes in multiples of the top grid cells (which are however unknown).
Fixed a bug in the generic output plugin that caused non-cubic grids to be cut to cubic grids.
Fixed a bug causing wrong shift-backs of particle positions for Gadget.
Disabled optimized unigrid mode as it did not work in all circumstances (issue posted).
