PL: add ZIP comments to regional partner factories

[breville]

This is just a convenience for my development work. Sometimes I use the factories to create some dummy regional partners in my local dashboard database, by running the following in dashboard-console:

RegionalPartner.destroy_all
if defined? FactoryGirl
  include FactoryGirl::Syntax::Methods
end

create :regional_partner_alabama
create :regional_partner_illinois
create :regional_partner_kentucky
create :regional_partner_newjersey
create :regional_partner_oregon
create :regional_partner_wyoming
create :regional_partner_beverly_hills

And then search for these using ZIP code at http://localhost.code.org:3000/educate/professional-learning/program-information.

Adding the ZIP codes to the comments makes for some convenient documentation when I'm trying to see the different types of results on that page.
