v0.5.0

• Added 4 additional Polished Hosting regions (see documentation for region argument of polished::deploy_app())
• App names (i.e. app_name) can now include upper case letters & spaces (Example: app_name = "Example App Name")
• added "cache" argument to deploy() app to set whether or not to use a cached build of your Shiny
  app on Polished Hosting.
• added "golem_package_name" argument to deploy_app() to allow for deploying Golem Shiny apps to Polished Hosting.
• removed options to pass an "account module" and/or a "splash page module" to the secure_ui() and
  secure_server() functions. These were experimental arguments for extending polished. We now have a better generalized solution for extending polished -- more to come soon.
• export the api_list_to_df function
• added new cookie_expires argument to global_sessions_config(), allowing you to set the cookie expiration for app users
