Adjust animation scale range.

The animation scale options are _developer_ options for a reason: They
allow _developers_ to assess and debug animations in the apps the're
developing. A max scale of 2 is not sufficient for that purpose, so
increase the scale.

Settings: set proper default value for tap to wake

The first time the display_settings.xml file gets inflated, the
PreferenceManager takes the defaultValue and persists it in the default
shared preferences file.

When we read the double tap to wake preference,
we assume it has a default value of true, which it uses until the user
enters Display Settings for the first time. At that point, the default
value is persisted, and every boot after will use the default value in
display_settings.xml.

Remove the default defined in the XML file.
