Capitalize location names and post titles

*Capitalize location names and post titles to prevent two db entries for the same thing
*Create method to display locations alphabetically.

@ChristopherThorsen @liantics - please let me know what you think.  Should be pretty minor stuff.
I wonder if something simpler might work, like:
def is_spam?
   spam == true
end

Since it's inside the post model, and posts have a spam method pre-defined courtesy of the database column name and the magic of Active Record, this should call the spam method on the post, and return true if the method returns true, or false otherwise.
