the code display is not correct in these situations:
1) if a '/*' appears in a string, the rest of the code is colorized as comment.
2) if two or more strings are in one line, all in between them is colorized as string.
3) if an instrument or UDO starts with 'S', it is colorized like a string variable
a simple example is attached (don't run it, just open in CsoundQt)
