Add --fix command line switch:

+    When the --fix command line switch is used, the script will also
+    make it possible to apply older patches that might have been
+    skipped.  For example: A database at schema version 65, with patches
+    since release 40, will not only be patched to the appropriate
+    release (specified with --release=NN), but all patches since release
+    40 (inclusively) will be tested.  If the patch identifier for an old
+    patch is missing from the meta table of the database, that patch
+    will be applied.
