Rr/server home ui tweaks

Created by: rrhyne

Small tweaks to the home page to fix a few design nits:

• panels at small sizes were not aligned with search UI because search UI did not have padding
• text size was larger than specified and did not match search box text size
• footer panels were a button instead of a div with a text link
• top margin was too large
• background color on panels was a poor design, causing a 'flash' when loading content
