ng2-tree rename is prone to XSS

[sfilipi]

Enable the right menu on ng2-tree.
Right click on a node -> Rename and enter the following as the new nodes name:

<img onerror="alert('hi')" src="/">

Notice the page runs the script.

The user input to the node name should be sanitized before use.

@sfilipi Thanks, for that - will do a fix ASAP!
