CStr: Indented comments more consistently. Made some parameters
pass-by-reference, made some others not. Removed some useless methods -
Length (use length or empty), GetSubstring (use substr), LCase/UCase
(use LowerCase/UpperCase). Removed operator[] bounds-checking because
VS2005 does that anyway.
Maybe fixed noncopyable warnings on VS2003.
This was SVN commit r4828.
