Global error management routine has been implemented in revision #5678.

This routine must be a static public method of the startup class, and 
must be named "Application_Error".

Inside this method, you can use the properties of the Error class to get 
information about the error.

If an uncatched error is raised while running Application_Error, then 
the program will abort with that error replacing the old one. Beware, 
this was not tested yet!

The IDE has been modified to try to save all modified files before 
aborting if an error occurs.

Enjoy!
