Version 4.2 release plans

[Ethan A M. <merritt@u.washington.edu>]

Unless someone chimes in with a set of new problems, 
I propose to put out a third and hopefully final release candidate
next week.  If all goes well, the plan is that the final 4.2 release
would be identical to -rc3 except for the various versioning tags

Changes since 4.2-rc2
=====================
- Document deprecation of "set size" to change image file size in pixels.
  (But version 4.0 behaviour is still maintained for default 'set term')
- Explicit size in terminal commands (e.g. "set term png size 500,300")
  guarantees output image size in pixels.
- 2D back/front settings are also honored in 3D plots with "set view map"
- Allow for quoted strings in csv data files.
- orientation of images drawn by "with image" is corrected for axis direction.
- Multi-dimensional parameters to "binary" and "with image" plot commands are
  now separated by colons rather than commas, and may be variables.
- In anticipation of libgd 2.0.34, gd.trm now checks for error from gdImageCreate
- Update Japanese documentation patch for terminals
