Accessing inflated layout + rectangular view(no rounded corners)

[rslowinski]

Hi, I've added new field 'inflatedLayout' which is assigned in setContentView and thanks to that I can later access reference to this inflatedLayout and make some runtime changes to it like changing value of TextView that is child of inflatedLayout. In addition I've added addRect() that is almost the same as addRoundRect() but without rounder corners :)
