[QScintilla] Unable to add new keywords into already existing lexers.

[Sarbojit Sarkar]

Thanks Phil for your response.
So you are saying subclass should work. It was not working because of
missing space? I did that but still it is not working. I mean even after
doing the changes suggested by you cpp lexer is not considering these
strings as keywords.
Also I try to put a breakpoint to see if "keywords" function created by me
is getting called or not. It is not getting called. I have not clue who is
suppose to make the call and why it is not calling.

Please let me know if I am missing something here.
