Android: Implement dw_entryfield_new, dw_entryfield_password_new() dw_button_new(), dw_text_new(), dw_status_text_new(), dw_checkbox_new() and dw_radiobutton_new(). Fix the signatures used in GetMethodID(), Android Studio can apparently do it autoamtically. Add a LinearLayout to the DWindows activity, use it as the content view so we don't need XML. dw_dwindow_new() will now return the LinearLayout instead of the Activity object... so the handle can be used with dw_box_pack*().
