Show contacts list immediately (instead of loading indicator) upon startup

[bittner]

At the moment when the Hangups app is launched it shows an animated loading indicator in the middle of the screen and scrolling credits at the bottom of the screen.

Loading Animation Gives No "Real" Feedback

This looks nice, acknowledged, but there is no feedback for the user about the progress the app makes while loading, which is especially tedious with slow connections and a long list of contacts.

Proposed Solution

• When the app is launched it should immediately show the contacts list, even when it's empty at the beginning, and add contacts to the list as they arrive.
• In addition there should be a loading indicator following platform conventions (this is probably a line from left to right on top of the screen, as with the browser app, or some similar progress indication if the number of items to be handled is not known in advance), or simply a network activity indicator ("hang on, I'm working ...").

This is partly related to issues #7 and #19 (not technically-wise but from a UI/UX perspective).

I agree, that should be done when implementing offline support.

@tim-sueberkrueb Oh, I almost forgot about the offline support :). You are right, that would go well together.
