Upgrading to the latest version of gems

I left `country_select` with the version as it was
using, due to errors I saw around pulling the country
names in the `Person` class. `CountrySelect::countries`
is not defined.

`jquery-ui-rails` have changed how it needs to be 
included in application.js and application.css. I 
fixed those.
