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'm wondering if it would be better from a site user perspective to do a comparison before attempting to save, then saving the original string if the capitalized version is unique, rather than saving the capitalized string.
