#30 Hide files in DIRDIFF mode - patch attached

[Anonymous]

Enable Hiding unchanged files and left-only or
right-only files in DirDiff mode. Patch attached,
although two internal consistency checks have to be
turned off since the number of lines displayed no
longer sums to the length of the diff.

designer made a bit of a hash of the changes required
to optionsDialogBase.ui, so that part of the diff is
way too big.

It would be great if you could incorporate this
functionality into future versions. I'd be happy to
take feedback on the patch and make cleanups if necessary.
