This allows app fragment use a less heavyweight fragment as super class
if they don't need PreferenceFragment. Using this class as base is
generally easier to set up robolectric tests too.

Refactor visibility logging from InstrumentedFragment into a mixin. And
apply mixin in remaining fragments.

Make all app lists (or at least all current app lists) use the same
base layout for icon, label, and sizing/padding. This way they
should look the same.

Improve how we compute the bar to better represent the
actual memory situation. Scale the per-app bars to try to
show them better in terms of overall memory use. And some
bug fixes.

Switch the proc status UI's memory use bar to be based on the
new total memory use computation, instead of showing that weird
"time spent in memory states" thing.
Also now have it link to a detail page that shows details of time
spent in memory states and RAM used by various things.
