- support BITMAP_CLEAR_MEMORY in create_bitmap()

- copying to clipboard now constructs a text_run_array for StyledEdit, that is added to the clipboard. In applications supporting it it pastes the text with the correct fonts and sizes, and the text colors.
- tried to find which line in source code the selection starts to open the editor there, but it's not finished so it's disabled.
