Added TAPR Open Hardware License

[GrimTheReaper]

I recommend you license your hardware under TAPR. Its an Open Hardware license, that:

* You may modify the documentation and make products based upon it.
* You may use products for any legal purpose without limitation.

* You may distribute unmodified documentation, but you must include the complete package as you received it.

* You may distribute products you make to third parties, if you either include the documentation on which the product is based, or make it available without charge for at least three years to anyone who requests it.

* You may distribute modified documentation or products based on it, if you:

* License your modifications under the OHL.
* Include those modifications, following the requirements stated below.

* Attempt to send the modified documentation by email to any of the developers who have provided their email address. This is a good faith obligation -- if the email fails, you need do nothing more and may go on with your distribution.
