[lazarus] New Bugs

Some new Bugs:


1. Project Options / Forms: If you send a autocreate forms to the available
   Forms. The code gets updated correctly, but if you switch the form back to
   auto, the source isn't updated.  


2. Can not start LAZARUS (Floating-Point (Invalid Operation)):
   If I start Lazarus I can see the splash, then only the window-frame
   of the Sourceeditor, but nothing more :(

   I have looked a bit into the code and I have found the position of
   the error. It is in the function GTKVScrollCB in gtkcallback.inc.
   Perhaps the same can occur in the second scrollbar function!?!
   The Floatingpoint-Exception is generated by a line around 1300. Which is
   PageI := Round(Page_Increment). I have looked, what is in Page_Increment
   and it is a very big number (4.294967296E+09), which looks like
   causing the problem. If I change the round to trunc it works. I don't know, 
   if then the result is the wanted? I have such a problem with floating point
   in another program, too. Could it be that there are some bugs in the FPC-Floating
   Point code??
   This is the output while starting:

3. The 'close all' menu item should close the open Project, too. Like in Kylix/Delphi.


4. In the 'remove from project'-Dialog nothing in shown.
