iOS agent v5.1.0

Improvements

• The iOS SDK will now collect an app build identifier when an app crashes, which will be displayed in parentheses beside the version number in the Crash Details page in RPM. This value defaults to the string CFBundleVersion that is specified in Xcode build settings. If CFBundleVersion is not specified the build identifier will not be displayed.
• A new API method +setApplicationBuild:(NSString*)buildNumber was added to allow specifying a custom app build identifier, overriding the default value pulled from CFBundleVersion.
