Deprecated wxSizer::Remove( wxWindow* ), s/Remove/Detach/ in most places.

Made wxSizer child list typesafe.  I've not added the wxList implicit
conversion kludge yet, let's see who complains first perhaps..

Deprecated wxSizer::{G,S}etOption in favour of {G,S}etProportion in line
with the parameter name change in the docs.

Added {G,S}etSpacer consistent with the accessors for windows/sizers.

Made all wxSizer index parameters size_t -- we support no sensible
interpretation for negative indexes in them.  Hopefully this will
cause no real problems, but code doing (eg. Remove( 0 )) will need
to change to use 0u to resolve the ambiguity with overloaded members.
This is probably a Good Thing though, ymmv.

s/FALSE/false/g ; s/TRUE/true/g ; s/wxASSERT/wxASSERT_MSG/g in sizer.{cpp,h}

Fixed (I hope) the brokenness in wxSizer::Show -- I have no code to test
this yet, so it's a blind change, but spacers should now be hidden correctly
instead of ignored, and it should be properly reversable over multiple
calls now too.

removed pointless private scoping around DECLARE_CLASS macros.

Replace 0's I added previously with NULL -- not like that will end the
email thread either..

Added Add( wxSizerItem * ) & co.  There are probably a couple of other
places we can usefully do something like this too.  Stopped short of
refactoring everything to raise some issues about sizer method recursion
on -dev.

Updated wxSizer docs some more, they are still incomplete but getting
better.

wrapped KeyCode in wxDEPRECATED, converted all (gtk build) instances
to GetKeyCode.  There may be a few left for other ports.

Fixed a couple of other random compile warnings along the way.
