Publishing 1.0.4.x version.
Modifying functions called while querying a websites, so we can know how many questions were added or updated.
Read list not loaded que querying from background task.
* Splitting RemoveQuestionsInReadListAndSaveAsync into two methods to avoid saving the questions file twice:
** One method only removes questions.
** Other mehotd removes questions, update tile, update badge and save.
* Moving tag-query logic to FeedsManager (new QueryTagAsync method is similar to QueryWebsitesAsync).
* Making LimitTo150AndSave asynchronous to make sure file is commpletely saved before the background task finishes.
Catching UnauthorizedAccessException from ShowAsync in debug mode.
Releasing 1.0.5.x version.
