Show .htaccess and index.php replacement option only when necessary

[LostKobrakai]

I'm using ProcessWire in a shared hosting enviroment where I need RewriteBase / to be enabled. Therefore I think it would be nice if the option to replace the htaccess would only be visible if there was in fact a change to that file. Maybe not as important, but the index.php would benefit from the same thing.

If you don't like hiding the checkboxes then at least some kind of warning that these files have changed would be nice.
