Minor fix/update for Conditional Select features

Fixed issue where Folder Tools tab did not hide when it should. Updated
Conditional Select > Select all that... options to work with multiple
files as input (i.e. when you select a JPG and PNG file, and click on
"Select all of same type", will select all JPG and PNG images, rather
than only all JPG images like before). Also fix focus issue when using
Conditional Select dialog.
