Drop 1.0 compatibility; document 1.4 migration

The FLTK 1.0 compatibility support by defining macro 'FLTK_1_0_COMPAT'
did no longer work since FLTK 1.3.x and nobody complained. Hence we
can safely remove this "feature".

Documentation changes:

 - Drop chapter 'Migrating Code from FLTK 1.0 to 1.1'
 - Drop chapter 'Migrating Code from FLTK 1.1 to 1.3'
 - Add  chapter 'Migrating Code from FLTK 1.3 to 1.4'

The removed chapters are still available in FLTK 1.3 docs.

- \page	migration_1_1	Migrating Code from FLTK 1.0 to 1.1
-
-
-This appendix describes the differences between the FLTK
-1.0.x and FLTK 1.1.x functions and classes.
-
-\section migration_1_1_color Color Values
-
-Color values are now stored in a 32-bit unsigned integer
-instead of the unsigned character in 1.0.x. This allows for the
-specification of 24-bit RGB values or 8-bit FLTK color indices.
-
-\c FL_BLACK and \c FL_WHITE now remain black and white, even if
-the base color of the gray ramp is changed using Fl::background().
-\c FL_DARK3 and \c FL_LIGHT3 can be used instead to 
-draw a very dark or a very bright background hue.
-
-Widgets use the new color symbols \c FL_FOREGROUND_COLOR,
-\c FL_BACKGROUND_COLOR, \c FL_BACKGROUND2_COLOR, 
-\c FL_INACTIVE_COLOR, and \c FL_SELECTION_COLOR.
-More details can be found in the chapter \ref enumerations.
-
-\section migration_1_1_cutnpaste Cut and Paste Support
-
-The FLTK clipboard is now broken into two parts - a local
-selection value and a cut-and-paste value. This allows FLTK to
-support things like highlighting and replacing text that was
-previously cut or copied, which makes FLTK applications behave
-like traditional GUI applications.
-
-\section migration_1_1_file_chooser File Chooser
-
-The file chooser in FLTK 1.1.x is significantly different
-than the one supplied with FLTK 1.0.x. Any code that directly
-references the old \c FCB class or members will need
-to be ported to the new Fl_File_Chooser class.
-
-\section migration_1_1_functions Function Names
-
-Some function names have changed from FLTK 1.0.x to 1.1.x in
-order to avoid name space collisions. You can still use the old
-function names by defining the \c FLTK_1_0_COMPAT symbol on
-the command-line when you compile (\c -DFLTK_1_0_COMPAT) or in
-your source, e.g.:
-
-\code
-#define FLTK_1_0_COMPAT
-#include <FL/Fl.H>
-#include <FL/Enumerations.H>
-#include <FL/filename.H>
-\endcode
-
-The following table shows the old and new function names:

-\section migration_1_1_images Image Support
-
-Image support in FLTK has been significantly revamped in 1.1.x.
-The Fl_Image class is now a proper base class, with the core 
-image drawing functionality in the Fl_Bitmap, Fl_Pixmap, and
-Fl_RGB_Image classes.
-
-BMP, GIF, JPEG, PNG, XBM, and XPM image files can now be
-loaded using the appropriate image classes, and the
-Fl_Shared_Image class can be used to cache images in memory.
-
-Image labels are no longer provided as an add-on label type.
-If you use the old \c label() methods on an image, the
-widget's \c image() method is called to set the image
-as the label.
-
-Image labels in menu items must still use the old labeltype
-mechanism to preserve source compatibility.
-
-\section migration_1_1_keyboard Keyboard Navigation
-
-FLTK 1.1.x now supports keyboard navigation and control with
-all widgets. To restore the old FLTK 1.0.x behavior so that only
-text widgets get keyboard focus, call the Fl::visible_focus()
-method to disable it:
-
-\code
-Fl::visible_focus(0);
-\endcode
