[CMD] Fix missing/misplaced newlines at end of displayed errors and prompts.
ConInString() should display a newline when it encounters the terminating
carriage-return pressed by the user for ending string output.
+ Remove the extra \n hacks in FilePromptYN[A].

Improve outputted strings from DATE and TIME commands.
+ Rename some STRING_***_ERROR defines.

/*
* REN.C - rename internal command.
*
*
* History:
*
*
* 27-Jul-1998 (John P Price <linux-guru@gcfl.net>)
* added config.h include
*
* 18-Dec-1998 (Eric Kohl)
* Added support for quoted long file names with spaces.
*
* 20-Jan-1999 (Eric Kohl)
* Unicode and redirection safe!
*
* 17-Oct-2001 (Eric Kohl)
* Implemented basic rename code.
*
* 30-Apr-2005 (Magnus Olsen <magnus@greatlord.com>)
* Remove all hardcoded strings in En.rc
*
* 25-Nov-2008 (Victor Martinez <vicmarcal@hotmail.com>)
* Patch dedicated to Myrjala because her comprehension and love :D
* Fixing following Bugs:
* -Wrong behavior with wildcards when Source and Destiny are Paths(FIXED).
* -Wrong general behavior (MSDN:"Rename cant move files between subdirectories")(FIXED)
* -Wrong behavior when renaming without path in destiny:(i.e) "ren C:\text\as.txt list.txt" it moves as.txt and then rename it(FIXED)
* (MSDN: If there is a Path in Source and no Path in Destiny, then Destiny Path is Source Path,because never Ren has to be used to move.)
* -Implemented checkings if SourcePath and DestinyPath are differents.
*
