richedit: Flip the big switch and encode actual CR and LF into end-of-paragraph runs.
Document remaining uses of bEmulateVersion10 and other checks for CRLF in editor.c. Make RTF reader emit a \r or a \r\n according to emulation, not a \n, which breaks streaming tests. Remove todo_wine from a bunch of riched32 tests that now succeed.
