Fix orientation of levels list

Browse source 
I forgot to add the PR_RTL_XFLIP flag to these menu options, so they
were always left-aligned, no matter what.

What actually took me a bit to figure out was how to make the level
completion stars work regardless of the contents of the title - the
stars should always be to the left of the title in an LTR language, and
always to the right of the title in an RTL language. Level titles can
contain bidi characters regardless of the level's rtl flag being set,
so I just let bidi handle all the level menu options, with some control
characters to make sure everything always appears in the correct order.
