changes in init url

group url set with slash and without slash also.
Dhiru, i think you made a change in urls, because groupchange url which you wanted to work ,was not going in to that context, may be it was reverting into browse topic or browse resource context. So you put that "slash" and that url gets worked. right? , or whatever might be the reason. Thats not an issue, you did a good job by allowing "/" in group url , but due to that slash("/") appended in line no 42 & 43, browse topic and browse resources apps are not working now.  Lets make it generic, why only group, we require all urls to be worked with "/" or without "/".

Lets make a common solution for all urls, as GN reported a bug regarding urls, that "if you put the slash("/") at the end of url it gives an error", so can we make something like for any url if it has not slash at the end , urls automatically take slash("/") appended at the end and goes into its appropriate app context" 

For that we have to define all urls unique from each other, we can do that by putting some extra contents in urls which uniquely identifies context. or we can use some other django's conventional patterns to define urls uniquely which allows slash"/" appended at the end of urls.
