Fix RTL appearance of new ToC icons

We had initially resolved the arrow-direction issue on RTL here by
swapping the two glyphs, but this put the arrow on the wrong side
of the greeked text representation in the icon.

Flipping it with a transform *seems* to work fine.
Tested in 6.1, 7.1, and 8.0.

Fixes for statusbar being hidden in landscape on iOS 8

Now checks for the actual status bar size and makes sure the
top menus get positioned and sized based on that.

Note there is an oddity where after doing a search or something
the status bar starts showing up in landscape again.... Might
have to tweak some of the other code about things wanting/not
wanting status bar to be adjusted.
