Graduations of mode to view a user's posts.

Graduations of mode to view a user's posts.

Now we can exclude blogs, and also exclude replies to other threads.

(Interestingly, the 'exclude replies' flag in the API only excludes
replies to _other_ accounts. So it keeps replies to _yourself_. One
effect of this is that if you post a multitoot thread, it all shows up
in this list. Of course the client could filter it too...)
