richmemo: modified patch by Silvio Clécio (#30852). (removed the use of Default() intrinsic, since it's not available in FPC 2.6.4. It's also a responsibility of GetTextAttributes function to fully initialized TFontParams structure).

* added SaveRTFFile function to utilities
* modified IDE RTF editor to allow saving a file
