audacity/src/commands/CommandManager.cpp
James Crook ce9938787c Use alpha or released or local manual for "help on selection". 
Previously this was hard coded to use the online alphamanual.
Some other help-on-errors paths were hardcoded to use the online manual, and did not use local help even if available, so these were changed too.

Also two naming changes in the code:
ShowHelpDialog() became ShowHelp() because it typically shows the help in your browser, only showing the help in a dialog under certain circumstances.
The helpURL parameter became helpPage since it is usually a page name that is then elaborated into a url.
The Link() function became InnerLink().

Some careful http -> https changes made too.

Audacity: A Digital Audio Editor
CommandManager.cpp
Brian Gunlogson
Dominic Mazzoni
*******************************************************************//**
\class CommandManager
\brief CommandManager implements a system for organizing all user-callable
commands.
It creates and manages a menu bar with a command
associated with each item, and managing other commands callable
by keyboard shortcuts.
Commands are implemented by overriding an abstract functor class.
See Menus.cpp for an example use.
Menus or submenus containing lists of items can be added at once,
with a single function (functor) to be called when any of the
items is selected, with the index number of the selection as the
parameter. This is useful for dynamic menus (effects) and
submenus containing a list of choices (selection formats).
Menu items can be enabled or disabled individually, groups of
"multi-items" can be enabled or disabled all at once, or entire
sets of commands can be enabled or disabled all at once using
flags. The flags should be a bitfield stored in a 32-bit
integer but can be whatever you want. You specify both the
desired values of the flags, and the set of flags relevant to
a particular command, by using a combination of a flags parameter
and a mask parameter. Any flag set to 0 in the mask parameter is
the same as "don't care". Any command whose mask is set to zero
will not be affected by enabling/disabling by flags.
*//****************************************************************//**
\class CommandFunctor
\brief CommandFunctor is a very small class that works with
CommandManager. It holds the callback for one command.

\class MenuBarListEntry
\brief MenuBarListEntry is a structure used by CommandManager.

\class SubMenuListEntry
\brief SubMenuListEntry is a structure used by CommandManager.

\class CommandListEntry
\brief CommandListEntry is a structure used by CommandManager.

\brief List of MenuBarListEntry.
