Improved search functionality for Models and Methods

Not highlight matching substring, and search across not only Method names but also Target names.

Includes upgrade to angular 1.3.2, to take advantage of `ngModelOptions` for debouncing to ensure smooth search functionality.

Also fixed a race condition where the Sidebar controller sometimes didn't get initialized prior to the initial route change broadcast, causing it to be empty as it was unaware which API to display models/methods for.
