Add SoFloPHP

Hi Davey, 
I've added SoFloPHP to the usergroups section, cleaned up the code a bit (please view the whole file at this version for a cleaner view of the clean up), and rearranged the user group logos in alphabetical order by City per Country. We hold a Ladies Night every month at our Boca Raton, Florida location. Please let me know if there's anything else you need from me in order to complete this pull request.
Thanks!
