Adding TE Connectivity FFC/FPC connectors and moving other such connectors.
Adding the script generated FFC/FPC TE connectivity connectors.
For now i created a separate lib for this type of connector as i suggested in issue https://github.com/KiCad/kicad-footprints/issues/134
If we decide to do it this way i also need to add the FFC connectors from Molex and Hirose. If we decide against it, then i need to move these connectors into Connector_TE-Connectivity.
About the footprints: I did not change anything on purpose. (Maybe text positions and line widths changed.)
