TclNewsChecker component

Taking into account the statistics on the this component using and trying to make modules more independent, the ability to perform file opening via the ShellExecute function of ShellApi by default was excluded from version 2.0.

ShellExecute(0, 'open', PChar(LocalFile), nil, nil, SW_RESTORE);
