Update to version 1.60.6.

Changes:

* read_line in input.c and e_load in earray.c handles now properly '\r'
  characters from DOS files.
* bug fix in metaps.c : postscript macros bar and fbar now handle hue the
  right way.
* handles wheel mouse to scroll the text window content.
* better event handling : test_key, test_code, syswait hack.
* drag and drop support from gtk/gnome apps (xdnd). it works with
  - ROX
  - Nautilus
  drag and drop from Konqueror does not work.
* popup menu for terminal editing
* modulo bug fix
* logspace, xlogplot, ylogplot, xylogplot, xlogmark, ylogmark, xylogmark
  enhanced and included in util.e (no more in a separate package).
* gcm, lcm, primes, isprime and factor functions added to modulo.e
* bug fix in project function in graphics.c
* util.e
  - added figure function which allow to draw quicly several graphs
    in the graphical window
  - xlabel, ylabel updates to fill the figure function requirements
  - xgrid : scale is now sent to the bottom right of the graph
  - added rotate, animate
* bug fix in my scan_dir function in main.c, which causes Segmentation
  fault
* bug fix in the way euler was dealing with input and lineinput in term.c
* new : antialiasing function to enable or disable antialiasing in
  density plots
* complete reorder in source file for future enhancements
* bug fix with solaris (scandir made portable)
* delete outputs menu item
