[lazarus] Lazarus messaging

[Shane Miller]

I have just updated CVS.  This version has two things changed:
When you resize a TForm, you can see it in the console window.  It tells you it's width and height so you know your getting the signal correctly.

The memo does not color the file correctly.  I screwed it up but will fix it later.  I am going to work on the resizing of child controls right now.

I am going to base it on the control's alignment property.  Each control should have an alignment.

Simply set the TStrings OnChange event:

Constructor TMemo.Create (AOwner : TComponent)

begin
  MemoStrings:=TStringList.Create;
  MemoStrings.OnChange:=@self.UpdateStrings;
end;

Any time the MemoStrngs stringlist changes, you are notified.
