[CLIENT] Right justified text is bad for input blocks

During champion ban/select the search box is right justified. That means if you click out of the box and back in the cursor will almost certainly be to the left of the text you've already entered, which isn't very apparent if you've only entered one or two letters. A new player's first instinct will probably be to hit backspace, which will do nothing. They think the search box is hosed and they miss the timer and dodge.
