Tool to open .chm documentation for all lexers

See above example about tool for PHP documentation. Create the similar tool

• File name: keyhh.exe
• Shell command: unchecked
• Parameters: -MyHelp -#klink "{CurrentWord}" "{AppDir}..\Docs{Lexer}.chm"
• Lexers: (empty)

This tool needs renamed .chm files: for lexer AutoIt it needs "AutoIt.chm" and so on. It needs .chm files in a single folder relative to CudaText folder.
