Add field and get/setters for "followRedirects"

This should go with a corresponding change to NetJavaImpl so that this field will determine whether redirects will be followed. Useful when it's necessary to get information from a redirect page or when reaching the redirect page is enough.
setFollowRedirects accoring to HttpRequest

Adds a call to setFollowRedirects on the HttpURLConnection so that this is set according to the HttpRequest.
Corresponding pull request: (this uses a method introduced in the pull request/change to Net.HttpRequest below)
https://github.com/libgdx/libgdx/pull/2054
Added exception and doc comments

Added an exception to setFollowRedirects so that GWT-backenders don't accidentally set it to false (which will not work). Also added doc comments so that these functions are added to the API.
