commented out the grass background, it was hard to read
added the icon into the link for the download data
Changed some labels and removed the html tags, they dont belong in a
view, unless its a template
removed excessive html and body tags
fixed a few of the login redirects to include a controller
added a success page after the user submits data for the Arthropods,
need to add it to the other types of data submission.. perhaps factor
this out into a seperate controller to be reused.
