Improved getNavigationLink Performance

[grahammendick]

Doubled the speed of getNavigationLink. Reduced the time to produce 10,000 links from 80ms to 40ms.

var stateNavigator = new Navigation.StateNavigator([
    {key: 'ab', route: 'a/{a}/b/{b}', defaultTypes: {b: 'number'}}
]);

function run(){
  for(var i = 0; i < 10000; i++){
    stateNavigator.getNavigationLink('ab', { a: 'abc', b: 123 });
  }
}

Made two changes in NavigationDataManager, each responsible for a 30% speed increase:

• Replaced new RegExp('_', 'g') with /_/g
• Replaced Object.prototype.toString.call with typeof
