Panic: Index Out of Range calling GetPlayerMap()

[sb89]

I received the following error when calling GetPlayerMap():

panic: runtime error: index out of range

It seems to come from err = proto.Unmarshal(response.Returns[5], mapObjects) in session.go. I'm not sure why it occurred but it only happened once after a couple of hours of testing. Perhaps we should check if the slice contains the required amount of elements before trying to access it?

[sb89]

It happened again. I believe it's probably because my session timed out, hence when it tries to scan it returns nothing.

@sb89 I think it might be wise to iterate the responses, return with no error if it reaches 5. Push the others to the feed.

This is the same as #16
