Enhancement: Add an "alwaysRebuildCaches" option to CatalinaPatcherFlags.plist or expose the button earlier

[sbytnar]

It would be nice to not have to sit like a watch dog, waiting for the Rebuild caches button to appear, only to usually miss it. An enhancement would be to expose the Rebuild caches button at the patch selection screen. Alternatively, add an option in CatalinaPatcherFlags to always do it. Thanks!
