Fix bug when changing displayed login state on 4.1.1
Update AsyncTask (mostly cosmetic changes) and remove its depenencies.
I can do without the dependencies now that minsdk==10.
Use a helper function to execute AsyncTasks in parallel.
While testing this I also realized that I am an idiot and that people on
pre-Gingerbread have had their AsyncTasks executed in series even though I
went out of my way to make them always parallel. Well now everyone gets
parallel goodness.
Remove some unnecessary SDK_INT checks now that minsdk==10
Remove Utility.commit() and all calls to it.
No longer needed due to minsdk==10.
Remove class_info_layout.xml. Unused.
It was causing warnings in AS anyway.
