* Add helper method to update checked items on portal_selections
before showing them to have its state changed.

* Disappear with old button of 'change state'
* Turn default new method to change state of checked items
XXX: this new method is not totally working yet, just first checked element
  have its state changed

* Fix its height to a dynamic format

* Verticalize 'menu-create' items
* Fix :hover border on 'menu-create' items, that was going out of item border
* Fix 'select-language' item layout

* Now it has a 'boxified' layout

* main UNG listbox now has a dynamic width
* listbox-tree-navigation now has a dynamic width
* Both 'height' are now dynamic
XXX: need to set a 'min-height' for main UNG listbox

* toogleLoading([true, false], message) is used to show or hide loading
  alert, with a dynamic message

* Improve documentation
* Add ';' to end of line

* Dynamize its 'width', so that it can show more options without
  breaking layout
* Add show effect when its opening
* Make it work synchronously, first getting user information

* When not logged in, just display "log in" form
  and stop processing unnecessary behaviours.

* Update the checked items before showing the dialog box,
  * Fixing the problem where only the old marked items were presented.
* Apply same layout of UNG Documents listbox table
* Dynamize the dialog 'height'

Now "Not implemented yet" message is located on the left side of UNG.
Slow a little its appearing effect.

Make "Refresh" button correctly reset UNG listbox checked items,
  asynchronously.

* 'ung_knowledge_pad' should remain in public state
* 'ung_document_list' gadget should remain in public state

Only loads UNG document list when on UNG main page.

Add "ung_knowledge_pad" to path

- It'll be, in near future, based on default Preference_viewHtmlStyle

- Search form now works asynchronous, linked with listbox gadget
UNG main javascript take care of linking it to work

- Inputs and img tags are not self-closed

Fix domain_url param for method unfoldDomain, that now receives string like "domain_url.domain_depth"

- Retrieves document list from user as JSON
- Also returns default/generic javascript used to get/update UNG listbox

Not necessary anymore, since now listbox is paging asynchronously like any other asynchronous gadget

- Implement change state button with javascript dialog
- Add div element to place listbox pagination buttons

- Refactor to apply new way to render ung listbox
- Increase performance by loading some elements only when necessary

Now unfoldDomain receives string like "domain_string.domain_depth", and does not receive 'domain_depth' param anymore
Also disable 'reset' command when rendering

Remove old listbox from main form, and add new one that links listbox from gadget

Add new UNG main listbox, based on an asynchronous gadget
