Guillotine Lib - Schema creation independent from site context

[GlennRicaud]

Allow the creation of schema outside of a site context. Instead of taking the types for the applications from the the site config, take them from the applications defined in an option. If not defined, take the value [app.name] as it is today

• Rename option 'applicationFilter' to 'applications'. Default to [app.name] as it is today
• If you want to have all the types from a site. You can pass the following value in the option 'applications'

  portalLib.getSite().data.siteConfig.map(function (applicationConfigEntry) {
  return applicationConfigEntry.applicationKey;
  })
