[numgrep] Typo in help. Factor operator is marked by 'f' not 'm'.

Fifth Beta Release v0.5

- Cleaned up a few bits of code in numsum.
- Adjusted copyright years to 2004.
- Added -c,-r,-x,-y options to numsum to allow it to sum columns
  and rows and specify which rows and columns you want.
  * Special thanks to the folks on #perl on irc.freenode.org for
    helping me out with the regex for this one.
- Added -<n> number hack to numsum to quickly specify the column
  number that you want to sum.  For now it only does columns
  1 through 9 because I need to figure out how to get past
  Getopt::Std to get the whole number specified.  Since this is
  such a hack, I might just leave it as is or drop it.
- Made some changes to the GOALS file in regards to what options
  are being planned.
