Fix README formatting and clear up language

Correct some problems with the markdown, there are some HTML tags that don't need to be there. Move the purpose statement to the top of the README, people need to see that right away :). Change title format to make it look nicer (I might be wrong). Remove any specifics about money or time, the project should not have any preconceived notions of how things are going to work this early on. Fix some typos and language.
