Changes to TAPSearchField

Now uses another dummy textField to show region picker.
Removed "Search" toolbar button when there is already text.
Instead, "Done" now always returns to the textField,
where the user can simply press "Done" on the keyboard
to search for the summoner.
New system icons

Added new icons that seem useful.
Some folder moving/organizing in /Resources/App
Merge branch 'chris' into dennis
Small changes to tableview cell aesthetics.

"Card" style cells like facebook.
Kind of sketch, just added a background UIView
into cell's contentView, but the images & such
are not actually inside "card" UIView.
(Doing so screws up current constraints).

Touched some constraints, feel free to fix.
Storyboard fixes
More storyboard fixes

Added item image views and game number label to the container parent
view.
