Refine statuses (#26)
Remote media is now dereferenced and attached properly to incoming federated statuses.
    Mentions are now dereferenced and attached properly to incoming federated statuses.
    Small fixes to status visibility.
    Allow URL params for filtering statuses:

	// ExcludeRepliesKey is for specifying whether to exclude replies in a list of returned statuses by an account.
      	// PinnedKey is for specifying whether to include pinned statuses in a list of returned statuses by an account.
      	// MaxIDKey is for specifying the maximum ID of the status to retrieve.
      	// MediaOnlyKey is for specifying that only statuses with media should be returned in a list of returned statuses by an account.

    Add endpoint for fetching an account's statuses.
