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.
