htaccess generator, Instruct user to save settings and return for rules

Nitpicking, another one of those AHAH-omatic things...
case:
When user changes htaccess selection on performance/boost page, the new rules are not generated until page is saved.

Solution 'add text message for user':
If a selection is changed, 'save settings' for new rules to be generated, then return to htaccess generator to copy newly generated rules.

There may be a better way to say it...
