replaced all (*) CStr / CStrW by-value params with const reference. hoo
boy.

please always perform this optimization (actually standard idiom) when
writing the code - it takes little work, tells the next guy that the
string won't be modified, and makes a large performance difference.

(* where possible.. a few require other changes and will follow later)

This was SVN commit r4151.
