Daniel Price (111):
      (opacity rendering) allow opacity rendering even when 3D perspective turned off
      (labels) bug fix with label identification if no real number read
      (d menu) single menu option only for units and calculated quantities, cleanup of interfaces
      (splash) updated version info + reduce verboseness
      (calc_quantities) possible seg fault fixed if no dustfrac present in data
      (write_data_phantom) splash to phantom handles multiple types + sink particles
      (sphNG) tempered some errors to warnings

      (splash) bug fix from earlier commit
      (write_phantom) minor cleanups
      (calc_quantities) BUG FIX: do not reset column limits unless new calculated quantity is added
      (units) bug fix: resetting units also resets dz unit
      (units) fewer prompts: units automatically applied if edited and auto-save units file
      (units) bug fix with double printing of units labels in units menu
      (units) suggest correct label if choose units from suggestion list
      (libsplash) include all interpolation routines in library build; remove dependency on labels module
      (libsplash) removed dependency on globaldata.f90
      (multigrain) print grain size info from multigrain dust file headers
      (labels) more intelligent units label on projection plots
      (string_delete) bug fix if substring to delete contains a trailing space
      (phantom) convert grainsizes in header to cgs for use inside splash
      (multigrain) automatic labelling of grain sizes in density and column density plots
      (interp3D_proj_geom) segmentation fault/out-of-bounds error fixed
      (interactive) adaptive limits on log colour bars show 3 dex range by default
      (limits) auto-adjust limits to device aspect ratio now works with multiple panels
      (interp) bug fixes with r-z rendering
      (shapes) BUG FIX with panel selection for interactive text box editing
      (shapes) further bug fix with previous commit
      Merge pull request #17 from mapetkova/master
      (particleplot) line joining particles reorders particles along x axis if ndim <= 1, fixes issue with line plotting in periodic domains
      (interp3D) compiler warnings fixed
      (interp_opacity) reduce verbosity of log output
      (interp) bug fix with parallelisation in openMP
      (interp3D_projection) added iverbose flag to interface to silence printouts
      (interp/libsplash) added iverbose flag to interface to silence printouts
      Merge pull request #18 from Evedel/master
