Note a user about updating podcasts after the app starts

[Michal Predotka]

I've noticed just after the app starts and new podcasts view is displayed, I cannot interact with the UI. I guess it's because the podcasts are being updated but there's no info about it on the screen. After a while a new podcast is added to the list (if there is a new podcast).
It'd be nice to add info, so a user knows why the app is not responsive for a while.

I tried fixing this one evening, turns out it isn't that easy. Meanwhile we are planning to relax the updating of podcasts. At the moment, the podcast list is updated on *every* app launch which seems aggresive and unnecessary. We will change that to update only once every 4 hours or something. Obviously this doesn't fix the problem, just a workaround until we rewrite the parsing backend in c++ where we can run it in a separate thread and unblock the UI.

Thanks nik90. Is it possible to add the spinning circle when the UI is locked?

adding to this it would be better if you gave the user the option of when they would like to sync podcasts within the podbird options. I would prefer a manual option that didn't sync until I told it to. cheers.

trunk rev 122 now shows the activity indicator when performing automatic episdes refreshing at app startup. Also the refreshing of episodes is done automatically only every 12 hours.

@Ramin, Can you create a bug report to track that request pls. It does help users on 3G connections and so on. So we will include it in the settings page perhaps.
