wxUniversal added to wxD

[Anders F Björklund]

Added (minimal) support for "wxUniversal" to wxD,
i.e. wxWidgets running with only basic OS classes:
http://www.wxwindows.org/about/wxuniv.htm


The main ports are still wxMSW (Windows NT/2K/XP),
wxGTK (Linux / GTK+ 2) and wxMac (Mac OS X 10.3+)

But running with wxUniversal is a way of getting
more "lightweight" widgets instead of the usual
"heavyweight" widgets - should that be desired.

The "wxX11" version should run on all the platforms
with X11, at least: Cygwin, Linux/FreeBSD, Darwin...

wxUniversal could also work for embedded platforms ?
