Removing an include specification.

[adutoit]

Hi.

It seems that once I have manually specified an include for a class, it stays there forever.  I.e. even if I remove an include statement from the "Import(s)/Headers(s)" box for a class, the include is always part of the generated header.  

Where is this information cached?  How do I permanently get rid the include statement?  I don't want to edit the generated header files everytime to remove redundant/deprecated includes.
