inject SharedPreferences (#4441)

Browse source 
(this one is for @charlag)

Calling `PreferenceManager.getDefaultSharedPreferences()` will read the
preference file from disk every time. This PR makes `SharedPreferences`
a singleton so they will only be created once at appstart (with a few
exceptions where it is hard to inject, e.g. in the `openLink` helper)
which should help getting our ANRs down.
