Started adding performance tests to the test suite
Added PDXOutlineLabel class to provide a way to display a 1px outline for text in a UILabel
Changed twitterName on Results view from UILabel to PDXOutlineLabel to give a 1px black outline around text to make it more readable on a light background
Fixed displayErrorMessage on all view controllers to display message immediately (there had been a long, varying-length delay previously)
Fixed bug where displayErrorMessage would not display correct message
Sped up display of... well, everything
Fixed failing test for getting URL
