Analysis: Resolve use support action bar lint warning

Warning Message: "Use AppCompatActivity.setSupportActionBar"

Explanation: "Use AppCompatActivity.setSupportActionBar"

------------------------------------------------------------------------

Renaming 'setActionBar()' extension function to 'initActionBar()'
automatically resolves this Lint warning as the 'setActionBar(...)'
naming no longer collides with the legacy 'android.app.Activity' such,
method, which was causing Lint to report a false positive Lint warning
in the first place.
