Bug #4273 - Document create_condor_taball and any other tool thats missing documentation

1. creation/create_condor_tarball
   - just updated usage so it had a little description.
.
2. doc/factory/configuration.html
   http://home.fnal.gov/~weigand/glideinwms.doc/master/factory/configuration.htm
   a. in the "Jump to" menu at the top
      - removed the top "Command Line" item.  It went no where.
      - added "Example Configuration"" line
      - added "Multiple Condor Tarballs" line
   b. in the "Related Links" menu at the top
      - added a "Tools" line (made sense as that is where some of the tools are)
   c. in the "Multiple Condor Tarballs" section
      - in step 1, added a reference (with a link) to the
        create_condor_tarball in the doc/components/tools.html doc
      - moved step 7 into step 2.  Seemed to make more sense there.
      - did a bit of a cleanup (fonts, bold) to make it more readable.
.
3. doc/components/tools.html
   http://home.fnal.gov/~weigand/glideinwms.doc/master/components/tools/configuration.htm
   - added a "Jump to" and "Related Links" menus at the top.
     They were missing.   Added links to each section.
   - added create_condor_tarball section with a link back to the
     http://home.fnal.gov/~weigand/glideinwms.doc/master/factory/configuration.html#tarballs
     doc.
