[Pythoncard-users] HtmlWindow component and simpleBrowser sample

I've added an HtmlWindow component and simpleBrowser sample to test the
HtmlWindow component. I do not know how this component will evolve in
PythonCard because it seems to be in flux in wxWindows and its main purpose
seems to be to support Windows-style Help files. I'm adding HtmlWindow, so
that we can at least experiment with it. The component doesn't support
normal event bindings for OnLinkClicked, OnCellMouseHover, etc. so we will
have to fabricate our own virtual events depending once again on how
wxHtmlWindow changes in wxWindows.

I did not add HtmlWindow to the resourceEditor and don't plan to until the
future of the component is clearer.

from the readme.txt:
simpleBrowser is not designed to be a full web browser.

The default URL is set to http://diveintopython.org/toc.html, but you can
change that in the resource file.

Due to limitations in HtmlWindow and the underlying wxHtmlWindow class, both
the HtmlWindow component and the simpleBrowser sample are likely to change a
great deal between releases. wxHtmlWindow does not have event bindings, nor
can you select the text in the control.

As of wxPython 2.3.2.1, the underlying wxHtmlWindow class does not send a
Host: header to web servers, so servers expecting a full HTTP/1.1 request
will generally return an error page. This includes almost all Apache
servers, including SourceForge. The next version of wxHtmlWindow and
wxPython should fix this problem so that the control works with more
servers.

I recommend working with HTML files on your local system to avoid HTTP
server issues.

The control does not support frames, JavaScript, and many other more
advanced HTML features. Just try it with files on your local system to see
what does and doesn't work. I think that it does give us a very simple way
to do non-editable styled text with embedded images, tables, etc. and this
is the area I would like to explore. It is not going to give us the power of
Mozilla or the Internet Explorer ActiveX control.

The underlying wxHtmlWindow control does support embedding other wxWindows
classes in HTML and while this is fairly advanced, it is also very powerful.
See the wxPython demo.py for an example. We should keep this in mind as the
framework progresses.

See the wxWindows/wxPython help file for more info on HTML classes.
