ZODB Components: Revert 'Allow to execute runUnitTest for bt5 Test Components' (a771dca4) to fix tests bootstrap.

The new syntax to load ZODB Tests Components is:
runUnitTest BT_TITLE:TEST_NAME

That commit was too adhoc as it was relying upon filesystem to load Tests
Components and was not behaving like any other Components (versions was not
available and other Components were not importable).

At the end, it would have meant that a Test Component ran through runUnitTest
and Live Tests (in ERP5 itself) would have behaved differently, thus instead:

1/ Install BT_TITLE dependencies and its test dependencies (new bt property to
   specify bt to be installed only for tests on a fresh instance).
2/ The site is loaded.
3/ Load the test by importing it like any other Components.

Avoid an extra step for developers by keeping the last Workflow History for
Components by default.

And Chameleon does not workaround by lowercasing them automatically.

The same mistake seem to be present in other parts of this test.

This is a followup to commit 8995b645
("always start transactions with begin() and make tic() commit automatically"):
there is now no need to use self.stepTic() instead of self.tic()

Most of UNG code is part of a UNGDoc skin created during bt5 install in order to not mess with rest of ERP5 UI code.
Adjust test (dirty) accordingly.

UNG code contains overrides of default ERP5 UI and KM UI which breaks it so add theme to its default skin selection (same way as KM).

Navigation tree has to be dynamic, near the list of documents

* 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.

Only loads UNG document list when on UNG main page.

- 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
