Help: Organize and revise the cmake-generators.7 manual

Move "extra" generators to their own section instead of duplicating them
for each corresponding main generator.  Divide the list of main
generators into command-line and IDE sections and sort the names within
each section.  Document the environment from which each kind of
generator may be used.

Add a section to each "extra" generator documenting which main
generators may be used with it.

-All Generators
-==============
+Introduction
+============
+
+A *CMake Generator* is responsible for writing the input files for
+a native build system.  Exactly one of the `CMake Generators`_ must be
+selected for a build tree to determine what native build system is to
+be used.  Optionally one of the `Extra Generators`_ may be selected
+as a variant of some of the `Command-Line Build Tool Generators`_ to
+produce project files for an auxiliary IDE.
+
+CMake Generators are platform-specific so each may be available only
+on certain platforms.  The :manual:`cmake(1)` command-line tool ``--help``
+output lists available generators on the current platform.  Use its ``-G``
+option to specify the generator for a new build tree.
+The :manual:`cmake-gui(1)` offers interactive selection of a generator
+when creating a new build tree.
+
+CMake Generators
+================
+
+Command-Line Build Tool Generators
+----------------------------------
+
+These generators support command-line build tools.  In order to use them,
+one must launch CMake from a command-line prompt whose environment is
+already configured for the chosen compiler and build tool.

+IDE Build Tool Generators
+-------------------------
+
+These generators support Integrated Development Environment (IDE)
+project files.  Since the IDEs configure their own environment
+one may launch CMake from any environment.

+Extra Generators
+================
+
+Some of the `CMake Generators`_ listed in the :manual:`cmake(1)`
+command-line tool ``--help`` output may have variants that specify
+an extra generator for an auxiliary IDE tool.  Such generator
+names have the form ``<extra-generator> - <main-generator>``.
+The following extra generators are known to CMake.
