Add STR type and can "<params>" now.HEADmaster

In bash, we can use args with space in it by quote the arg itself,
like `grep "test C"` or `cd "dir 1"`. I make it. Add a STR type in
flex, and deal with it specially while append it as an argument
(malloc a new str space, copy the content of STR into it, then free
the STR string, add the new str as an argument).
