Set 'lang' and 'dir' attribs on HTML body; fixes basic RTL articles

Fix for crashes when nav items tapped while views are transitioning.

There had been code to debounce the "W" menu, but another crash was
discovered: Tap edit pencil, then tap "X" icon and "W" menu icon in
quick succession. CRASH! This patch is a generic solution which
handles both of these crashes and should prevent any similar crashes
elsewhere.

Added login option to wikitext editing workflow.

New "TopActionSheet" category for easily presenting an
array of views to be used as buttons appearing under the
navigation bar. Can present views in vertical or horizonal
layout and animate layout changes.

Various small bug fixes and refactoring too.

add a bunch of new strings files to the project so they get included in the build

yay for xcode for making us manually add every file!
