Replaced old wxSizer,

Converted two of wxGTK's standard dialogs to use them,
  Applied two fixes to wxDC code,
  Made wxRadiobox a little smaller,
  Added sizer.h to wx.h

-Algorithm:
-
- Each sizer has a Layout function.
-
- wxExpandSizer::Layout                  ; E.g. for resizeable windows
-
-   - parent size must be known (i.e. called
-      from OnSize or explicitly)
-   - call Layout on each child to give it a chance to resize
-     (e.g. child shrinks around its own children):
-     stop when all children return TRUE, or no change
-   - evaluate constraints on self to set size
-
- wxShrinkSizer::Layout                  ; E.g. fit-to-contents windows
-                                        ; Perhaps 2 rowcols, one above other.
-
-   - call Layout on each child to give it a chance to resize
-     (e.g. child shrinks around its own children):
-     stop when each returns TRUE, or no change
-   - fit around children
-        (what if some want to be centred? E.g. OK/Cancel rowcol.
-         - done by centring e.g. bottom sizer w.r.t. top sizer.
-           (sibling relationship only))
-   - evaluate own constraints (e.g. may be below another window)
-   - IF parent is a real window (remember: a real window can
-     have only one child sizer, although a sizer can have several child
-     (real) windows), then resize this parent WITHOUT invoking Layout
-     again.
-     Frame and dialog box OnSizes can check if the sizer is a shrink
-     sizer; if not, can call layout. Maybe have virtual bool AutoSizeLayout()
-     to determine this.
-
-How to relayout if a child sizer/window changes? Need to go all the way
-to the top of the hierarchy and call Layout() again.
-
- wxRowColSizer::Layout
-
-   - Similar to wxShrinkSizer only instead of shrinking to fit
-     contents, more sophisticated layout of contents, and THEN
-     shrinking (possibly).
-   - Do the same parent window check/setsize as for wxShrinkSizer.
