Add an -F option to the redo.py script to selectively re-run only those failed sessions whose filenames contain the component(s)

specified.  For example:

    ./redo.py -F x86_64 -n 2012-05-07-15_28_24

will redo the failed sessions under the 2012-05-07-15_28_24 directory, but only for session names which contain 'x86_64' in it.
