v1.6.17

• Added warning in the log file and in clink-diagnostics (Ctrl-X,Ctrl-Z) when ANSICON is detected on Windows 8.1 or greater (it's unnecessary, less functional, and greatly degrades performance).
• Added language info in clink-diagnostics when the code page is not 1252 (for easier troubleshooting).
• Fixed finding argmatchers registered with exact names (typing foo couldn't find an argmatcher registered as c:\dir\foo.exe because it accidentally looked for c:\dir\foo.EXE).
• Fixed #631; script error after cmd when the current language is German.
