Last few updates and fixes before prototype goes to stakeholders

[gklarenberg]

• [x] Show WQ station names longer
• [x] Write out shapefile names
• [x] Write better explanation on main page
• [x] Check OFW shapefile: showing mangroves??
• [x] Maybe/hopefully add HAB data stations on the main page

For now I will leave the plot underneath the map. I am also terribly torn about this, so I am curious what users have to say (there will be more functionalities added over time, such as different types of plots, options to compare sites, so it will be a puzzle to figure out what to put where…)

This was all done - WQ station names and better explanation was done as part of #43 (for the second prototype)
