Changes from 1.10 to 2.0
-----------------------------
*  Added the /Q switch.
   Quiet mode. Program will not display messages on screen. Overrides
   /P and XFFConfirm=Yes. Error messages will be displayed.

*  Added the /T[C]="text to search for" switch.
   Search inside the files for a string. /T makes a case insensitive
   search, while /TC makes a case sensitive search.

*  Added the /F=xxx switch
   Limits the number of files found to xxx files.
   The program halts when xxx matching files are found.

*  Added the /W=filename switch  
   Writes the full name of the matching files to a file.

*  Added the /N=[+|-]xxx switch
   Find files newer/older than xxx days

*  Added the /E="command parameters" switch 
   Execute command on matching files.
   See XFF.TXT 3.3.9 and 7.0

*  Added the /VER switch.
   Displays version information. (Version and internal revision)

*  Changed one of the filespecs.
   Because of the use of double quotation marks in some of the other 
   switches I changed the ("xxxx")*.* filespec to ('xxxx')*.*.
   It now uses single quotation marks. See XFF.TXT 3.2

*  Changed the /A switch.
   You can now search for files without specific attributes by adding 
   a - before the attribute.
   /A=h-s-r would search for hidden files that are not system or readonly.

*  Changed the /D switch.
   You can now search for files NOT stored within a range or on a specific
   date. /D=~011297..311297  /D=~011297

*  Changed the /S switch.
   You can now search for files within a size range and NOT within a size 
   range. /S=100..512  /S=~100..512

*  Documented the errorlevels. See XFF.TXT 3.5
