iPad: Added navigation arrows to the main screen's title bar.
Visual fixes for iOS 7 (table cell: margins, font weight, etc.).
Added UIColor+HexColor category and BRUI class with UI-related utility methods.
"Normal" deceleration rate for UIWebView so it feels the same as in native controls (e.g. in a table view).
B-26: Showing BRDatePickerViewController faster by adding them programatically instead of in XIB.

Not tested on real devices with iOS 6, though. Makes almost no difference in the Simulator.
FR-6: Tapping inside the web view no longer causes jumping of the content (while hiding nav bar and status bar)
FR-8: Larger font sizes available on iPad
FR-6: Another approach for fixing jumping content when tapped in web view + navigation bars are no longer translucent so its color matches splash screen's.
Fixed "washed-out" navigation bar color for iPad as well (iPad fixed in previous commit).
B-21: Background behind web view matches web view's color (works for night mode too). Fixed scrollbar color for night mode.

Visible before content loads, and when pulling web view down or up too far.
iPad / Settings: wrap boolean cells to multiple rows if necessary
iOS: resize celebration cells automatically
iOS: about menu
