Title: Change fixed width of logo in header to max-height. 

Addresses issue #1045.

This isn't an ideal solution for that issue, since it doesn't reflow the body container to accommodate a larger logo. But, max-height allows a more fluid height and width of the logo and will use css to resize a larger logo to a size that fits in the header.
