Connect to SpaceRepository without knowing the ip or port number.

[TheAIBot]

Currently to connect to a SpaceRepository you need a to know both the ip address and the port. This leads to hardcoding the two as that's the easiest solution.
I would like a method where the input is a spaces name and the output is a list of URIs that contain a space with that name on the network the computer is connected to.
Something like this:

List<String> URIs= RemoteSpace.findSpaces("tetrisGameServer");

This should also solve the second issue(sending ip and port to RemoteSpace from SpaceRepository) discussed in #18.

Thanks @TheAIBot this sounds like an interesting feature for pSpaces. It will take us a while to decide the best way to deal with this, though.
