Wiki should have "register" and "how to edit" links beside login

[wsargent]

It's not clear that the website is a wiki that can be edited by people with a dojofoundation.com account from the main page. The only information showing how to register is shown after clicking on the "login" link, which usually wouldn't occur to people who don't have an account. I didn't know about it until wildbill told me how to do it on IRC.

Adding some text indicating that the docs can be improved and edited if you register would help a lot to improve participation and involvement.
