All contributions to the kicad library must follow the KiCad library convention

Thanks for creating a pull request to contribute to the KiCad libraries! To speed up integration of your PR, please check the following items:

• Provide a URL to a datasheet for the symbol(s) you are contributing
• An example screenshot image is very helpful
• Ensure that the associated footprints match the official footprint library
  • A new fitting footprint must be submitted if the library does not yet contain one.
• If there are matching footprint PRs, provide link(s) as appropriate
• Check the output of the Travis automated check scripts - fix any errors as required
• Give a reason behind any intentional library convention rule violation.

• Filter should be SOT?23* like other parts in the lib:
  
• The FP-name in the description should have the -6 suffix.
• The pin positions do not conform to KLC. But they are the same as the existing symbols. And the user should be able to use this one as a drop-in-replacement. So its okay.
