Suppressing the reloading/recreation of controllers and views upon query string parameter changes

[cbayram]

The reloading and recreation of the controllers and views when modifying search parameters prohibits any smooth UI as the DOM as well as scopes are discarded. The current 'reloadOnSearch' stops the transition, however it fails to update the $location.search(), more importantly, it fails to reflect the changes to the $stateParams which applications rely on for reactive code ($watch).

The goal is to be able to perform UI animations, react to $stateParams changes and maintain state in the url. I've created a pull requests #1037 and would love your feedback.

I've tried to avoid breaking existing functionality and resorted to creating two new configuration variables.

The configuration of 'reloadOnPath' and/or 'reloadOnQuery' being set to 'false' will update the url, update the $stateParams and suppress the reloading of the controllers and views. One can specify the same configurations when using $state.transitionTo() as well as other wrappers around it ($state.go()).

@nateabele, has your dynamic-params branch been merged into master yet? If not, do you know when that'll happen?
