There are some apps on the app exchange. Search for bug tracking in app exchange or google and it should come up with some apps. See if these help you.
BugHerd can be used for visual issue tracking on salesforce pages, using a browser extension. BugHerd allows you to point out elements on the page which can be extremely handy. It takes a screenshot as well. For version control you would have to use GitHub or Bitbucket as it doesn't specifically integrate with Salesforce. See http://bugherd.com/features
