Changes

bug #14804 : The textarea in the modal window stays now in the limits of the parent area

bug #14804 : missing fieldset.css

Bug #14869

NodeService#createNode methods return now the new NodeDetails instead of
the NodePK of the created node.

Check directly the nullity of the returned ProfileInst object after the
invocation of ProfileManager#getProfileInst(...) method in order to
avoid to spread the nullity possibility of the ProfileInst object up to
the chain of call.

bug #14781 : Entry Paste is now possible at the root level, as the same way in the contextual menu of a node.

Bug #14869

Take into account the signature change of the NodeDetail#createNode
methods.

When pasting a topic into another one, from a copy or a cut, take
into account in KmeliaService the specific rights of a parent topic to
the node in which the topic is pasted.
