Added "wiki" pages

I finally understand how to use Github, and I created a github version of the Electronics Parts Suppliers directory I started on the message forum. You are welcome to pull it into your github page. :-)

I haven't done much with Arduino lately, in the spring I almost had a Garage Door monitor working, but I wasn't happy with it. I ended up getting a Raspberry Pi last week and ported the project over to it. You can see the code on Github if you are interested.
