Fixed tab selection on page reload.

jQuery tabs by default will display the first tab, so reloading a page
or opening a page from bookmark may not show the active tab correctly.
The nav_select_tabs() has been added to get the list of active tabs from
the hash values in the URL and then activate the appropriate tabs. It
will be called during page initialization and whenever the hash values
change.

The navigation.js and webui.js has been cleaned up to better utilize
jQuery API. jQuery selectors are used to create DOM objects that can
be used by subsequent codes. Tab selection handler is now added to the
tabs object instead of anchors. The change event no longer needs to be
triggered manually.
