Fixes#5919
Created a url_for function module to be used by different javascript
modules to use the same functionality of flask at client side.
A python module can expose the list of endpoints, used by its
javascripts, by overriding the 'get_exposed_url_endpoints(self)'
function.
In this patch, we have modified all the browser modules to use this
function. It will allow us to move the majority of the javascript
modules of browser nodes from templates directory to the static
directory.
TODO::
- Move these javascripts modules to the static directory.
- Use this function in all the applicable javascript modules.
e.g. tools, miscellaneous modules
aciTree.
Also - fixed few CSS specifically for the preferences dialog.
Returning the sorted preferences from the server, so that - it lists
down in correct order.
