Edited 'main.js'

- Changed 'main.js' so that a blank address can be used in making an
embeddable map
- NOTE TO SELF: The previous commit totally overwrote 'main.js' from
5/3/2013. Make sure the necessary parts from the May commit (i.e., where
the infoWindow text changed depending on which HTML file calls the
Javascript file) are included in the final version of this feature.
Changed embed button functionality

- Instead of a popup window, embed code now appears in a text box next
to the embed button
