V151

 Changes V146: Works OK
 Changes V147: Line numbers removed and code cleaning in Logviewer.h
 Changes V148: Replace snprintf(sptext, sizeof(sptext) with Tekstprintf. Added Option Y { and G from web page menu not possible
 Changes V149: Flashing warning text Option Y or G not possible in web page menu. Optimized bool GetNTPtime(bool printit) . Mem.TimeMinute used to turn off time printing every minute
               Major cleanup and bugfixes
 Changes V150: Stable version
 Changes V151: functie FILENAAM \ ook voor MacOS/Linux /.  Mem.TimeMinute       = 1;    // Print time per minute (1) or hour (2)
