Lea convert home page from old site

This is mostly for the purpose of getting bootstrap 3 installed and running. The majority of the content is boilerplate, and will be replaced when actual projects exist (thus the use of non-breaking spaces, instead of css). 

I extracted the ignorable bits into partials. 
The dashboards/index.html.erb and the _header.html.erb partial are the only bits with any functionality.

When I get back to formatting, after projects exist and people can donate money, I'll play with converting the old bootstrap 1 css code to work with bootstrap 3.
Beautiful indentation!
