Refactor SettingsUI

Refactor SettingsUI

[Issue#]   https://bugs.tizen.org/jira/browse/TT-153
[Problem]  Check boxes in settings menu can't be clicked.
[Cause]    Invisible platform rectangle covers this screen area.
[Solution] Refactoring settings UI code by replacing unneded genlist,
           with layout inside scrooler. Also added possibility to click
           check box labels as a complementary fix for platform issue
           with invisible rectangle.
[Verify]   Open More menu -> Settings and check if check boxes: Cache,
           Cookies and History can be changed by clicking their labels.
