title: AngularJS $route service undesirable hash issue
body: <p>I'm working on a big project. This project already has complicated structure. Most pages are generated on server-side with Twig. 
   Now we move the project to AngularJS.
   It is not possible to use angular-way routing on whole project just now. But somewhere, it is necessary.</p>
  
  <p>And here comes our trouble.</p>
  
  <p>If I add 'ng-app' in html tag, for example, on some pages angular add hash in url.
   And what is strange for me, that it's not everywhere.
   On start page (project/profile9868766), url is clear as it is. But on some other (project/community/list), angular does something like that: project/community/list/#list .
  And it is extremely undesirable.
   There are no any angular routes, configured in $route service yet.
   Please, help me to find out what causes that behavior, and what should i do to make all the things to go right way.</p>
  
  <p>I want to add ng-app in html tag and not get any troubles with existing code, that may use hashes. And I want to use angular directives, controllers and other stuff, including $location service to set and track hashes on some pages. And later move everything to Angular and only after that start using Angular routes.</p>
  
  <p>Thanks!</p>
