Show progress bar for stats screen

[indianpoptart]

If the stats file is too big, when clicking stats, the app hangs for a few seconds, then loads the graphs. Instead, do all the loading in an async task, and possibly show a progress bar on each graph(if not show a small splash screen or show progress bar on action bar)
