Updated logo and log in

There were comments at the CESI conference regarding the logo that anseo.net uses.  Generally, there was confusion with the first letter and many people were typing the “@” symbol instead of the letter “a”.  I have introduced a new logo, which aims to address this.
Also, logging in has been made easier.  You can now log in by typing in your username and password on any screen on the blog.  once, logged in, you can choose from a list of options, which will appear on the right hand side of the screen.
