Draft SPACIOUS page updates

[sfregosi-noaa]

Selene will take a first stab at updating the glider page:

• add team member names
• add SPACIOUS logo
• Add name/acronym
• update action items to state our objectives
• Create placeholder pages for propagation, occupancy, and species/sperm whales
• Upload a favicon #1

I modified our glider content on the home page and on the glider page (renamed it to 'Mobile recorders') and created a few empty pages. I didn't map to them yet since they don't contain anything but can if that would be useful. Take a look and let me know if there's more content you think we could add now.
