Remove recently-merged uploadify components, since uploadify got removed
sometime between branch creation and the (long overdue) merge.
Follow-on to recent user profile bug fix - function doesn't need args.
Make clean URLs work for K3 - like G3.0.x, just uncomment block in .htaccess.
Revise Access::update_htaccess_files() to remove "index.php" for robustness.
If htaccess files are generated with "index.php" then clean URLs are turned on,
they won't work anymore.  This ensures that it works regardless of whether or
not clean URLs are used.
