Updating submodule version.
Updating help content.
LauncherOptionsDialog can now implement a Help button.
However it may be preferable to display the help text
within the main panel of LauncherOptionsDialog, rather
than having the user open up a separate window.
Displaying busy cursor while loading help for the first time.
Updating submodule version.
Removed unused code from LauncherOptionsDialog module.
Fixed a couple of minor issues observed while testing against
wxPython 2.9 (as distinct from 2.8).  Also observed a layout
problem with the wx.RadioBox in the options dialog while testing
against wxPython 2.9, but that hasn't been fixed yet.
Adding psutil to dependencies.
Script for automated Mac builds.

It doesn't yet support the pretty DMG background and icon
layout, which result from the manual Mac builds.

There seem to be race conditions or something strange going
on with the Apple Script which tries to make the DMG look
pretty.  The manual method of building the Launcher's Mac
DMG is described on the following page within the CVL's
public wiki:

Script for automated Mac builds can now create "pretty"
DMG background.
Updated usage information.
Avoiding asking the user if they want to submit a debug log
when they cancel from the PassphraseDialog, because they will
probably be shown a second dialog anyway after canceling, telling
them what to do if they have forgotten their passphrase, so
displaying a 3rd dialog (Do you want to submit a debug log?) is
probably just going to annoy users more than it will help them.
Adding some logging info which can easily be grepped for
in the submitted debug logs.
Windows builds are put in current directory now, instead of
C:\launcher_build\
Ensuring that we build a 32-bit application bundle.
