	* ControlAdjuster.cc: New file, helper to move elements of a dialog 
	along when the it's resized. 
	* ControlAdjuster.h: Ditto.
	* Makefile.am: Add new source files.
	* proppage.cc (PropertyPage::DialogProc): Adjust some common
	controls (Cygwin icon top right, separator below) when a page is
	resized.
	(PropertyPage::PropertyPage): Dito.
	* propsheet.cc (IsDialog): New. Test whether a window is a dialog.
	Used internally by resize logic.
	(EnumPages): New. Used internally by resize logic: resizes the
	property sheet's individual pages.
	(PropSheetWndProc): New. Hook for the propery sheet window proc.
	(PropSheetProc): More style tweaks, add maximize box and thick border
	as well. Hook into the property sheet's window proc.
	(PropSheet::AdjustPageSize): New. Adjust the metrics of a single page
	to fit nicely into the property sheet. Part of resize logic.
	* res.rc (All dialogs): The top-right Cygwin icon and top separator
	now have IDs distinct from IDC_STATIC, so their metrics can be 
	adjusted upon a resize.
