Displaying UrlHistoryList refactoring (moving class, focus chain).

[Issue]    https://bugs.tizen.org/jira/browse/TT-161
[Problem] UrlHistoryList was not included in focus chain and was not
always visible in a WebPage view.
[Solution] UrlHistoryList is moved to WebPageUI. UrlHistoryList is
added to focus chain in 'WebPageUI::refreshFocusChain'. Inserting
focused item's content to uri entry.
[Verify] Displayed UrlHistoryList (QuickAccess view and WebPage view)
should be included in focus chain. Focusing out from list and from
UriEntry should cause list's scroll out. Focusing on item should
change uri entry content.

What is not solved yet: 1) list's width is not adapting to QuickAccess
url width. 2) 'web_view' content in WebPage view is sometimes
colliding with list's focus chain 3) If list is displaying small
number of elements, it's partially covering web page view (blocks
cursor focus events).
