Implement new 'Topics' methods

[boncey]

There's a test (CompletenessTest) that interrogates the API and lists methods we've not implemented yet.
I'm gonna raise separate issues for each thing that needs implementing which will make it easier to split the work.

These are the Topics methods that need to be implemented.

• flickr.groups.discuss.topics.add
• flickr.groups.discuss.topics.getInfo
• flickr.groups.discuss.topics.getList

Hi, is there a milestone that can be attached to this task? Looking forward to this api.

Hi, these methods seem to have slipped through the net - thanks for alerting me.
I've made a new milestone for this and a few other completeness related tasks.
No due date set as yet as my time is limited but hopefully shouldn't take too long.

I've gone through and implemented all the gets from groups.discuss.topics and groups.discuss.replies in my commit e610076; however in that commit all instances of "parameters.put(Flickr.API_KEY, apiKey)" need to be removed in GroupDiscussInterface.java
