Enable debug logging in gnugettext.pas

gnugettext.pas has got a conditional define called DXGETTEXTDEBUG. If it is defined, various debug messages are written to a MemoryStream. That won’t help much, if you can’t read that stream, so you need a way to write that stream to a file.

Guess what, that’s easily possible. Just call DefaultInstance.DebugLogToFile passing it a file name to which you want the log to be written. An additional parameter determines whether the file should be overwritten or been appended to.

In that call, the whole memory stream gets written to that file, so no log messages get lost. Also, any subsequent log messages will be written directly to that file instead of the memory stream.
