Addition of small script and script output

Hi Brennan and Doddy, I'm doing this pull request to provide a small sed script I've used that takes the sbv caption file as input and output a file which will ultimately become an html5 document. I still have a long ways to go with editing. There will be some normal editing work applied also. 

I request permission to use the "According to Pete" logo image in the html that I am imagining. Or perhaps Sparkfun can edit that in if . My next pull request will include an images directory under the web directory.

I want to thank you both, again, for providing the captions to me. It really means a lot to me to know what Pete is saying in his video. I am amazed at your kindness in doing this, and I hope to give freely of my own skills as well.

Thanks
