Enhance file path to navigate through the taxonomy tree for skill and knowledge

[vishnoianil]

Currently file path input box in the skill and knowledge form requires user to provide the path in the taxonomy tree, where they want to add their skill or knowledge. Currently this process is pretty manual. User needs to go through the taxonomy and determine the directory in the tree structure where the skills can be added and provide that path in the file path input box. Overall user experience of current implementation is not very user friendly. Having an option where user don't have to leave the form to determine the taxonomy path, would be the desirable.
