Function auto_need can't handle dictionary requirements

[ldaverio]

Hello,

as per Deform's documentation : Specifying Widget Requirements, a requirement may be specified:

• either as a 2-tuple (library, version)
• or as a dict { requirement_type: requirement_location(s)}

The auto_need function, defined in file js/deform/__init__.py, handles only tuples, hence can't be used for resources like TinyMCE. I'll try to see if I can write something clean, if so I will submit a pull request.

Laurent.
