Revision 89981

     All mod_autoindex query parsing is now quietly quashed with the
     IndexOption IgnoreClient.  The IndexOption SuppressColumnSorting
     still drops the column sort <a href>'s for the column headers, but
     IgnoreClient is required to ignore these Query options entirely.

     Introduced new mod_autoindex query argument parsing for F=[0|1|2]
     to allow the client to select plain, FancyIndexing or HTMLTable
     formatting, V=[0|1] to inhibit or enable version sorting, and
     P=pattern to return only specific files.  The old Query Arguments
     were reorganized as C=f for sorting column 'f' (same N, D, S, or M
     as before), and O=A|D for ordering ascending or descending.

     Docs and an Example are provided in mod_autoindex.html
